.mov and .mp4 not display correctly or export

I've been running Windows 7 (x 64, SP1, Ultimate) for awhile now but just recently I've been having problems with of mov and mp4, that seems, with Media Player and Live Movie Maker.

When open in Media Player, the audio will play very well, however I just get a black screen. When they are imported into Live Movie Maker, they will appear in the preview area, but trying to export the results to another screen or a green screen (or sometimes even a black screen with a green line to the left).
I have all the latest updates Windows installed from today and tried to download codecs from http://www.microsoft.com/en-au/download/details.aspx?id=507, but after the validation, the page does not exist.
They play fine in VLC, so it looks like a problem with the codecs by default, but I don't know how to update.

  • Why pages such as natwest and ELC not displayed correctly? It's as if their text is too big, yet other pages are very well?

    I have abrand new laptop ASUS with a 11 and a half inch screen. I've updated Windows system and uses the latest version of firefox. I went through all the advice in the section including firefox help clear the cache and cookies, and also check all the settings for the text, but none of this has fixed the problem. For example when I connect to my Bank in the text line is that big it does not fit in the boxes of natwest screen, so I can display all of the text and it gets mixed together in some places. With ELC, a good example is the menu at the top of the page which shows all categories of products they sell for you to click on. Because writing is too big it does not display properly. Im not sure what else to do in crrect. Can anyone help?

    I noticed in this screenshot that you have increased proportional size from 16 to 24.

    This helps to redefine 16?

    You can see the default values in a screenshot in this article:

    You can reset the fonts preferences on the topic: config page by default via the context menu.

    • Open the topic: config page through the address bar and do a TEXT search through the top search bar of the about: config page.

    Add code to the userContent.css file.

  • M/S using wireless keyboard 800 and some characters are not displayed correctly

    Have just connected a new wireless keyboard M/S 800, and some characters are not displayed correctly. For example, I get "when @ (update 2) is pressed on the keyboard and the £ runs it shift 3.» Am currently using XP SP3.

    No problems with my original keyboard, Wired.

    Hi simoncd.

    What is your location.  The reason why I ask this is that your keyboard is set to the standard UK layout.  Looks like you have the keyboard for the U.S. keyboard layout.  Shift + 2 is the "on the UK keyboard, @ on the U.S. keyboard."

    To change the keyboard settings you must go to "Control Panel", then "regional and language options".  The first page allows you to set the number format and character relative to your location and also set the location.  Check these and modify accordingly so badly.  You want to then go to the second 'languages' tab and click on the button "Details".  Here you can set the default keyboard.  This changes if necessary.  This should, hopefully restore your keyboard to the presentation that you want.

  • Photoshop starts does not display correctly?

    After some time working in PS it seems stop is not displayed correctly. Things will happen as suddenly a solid black rectangle will hide the part of the image. The rectangle can appear suddenly if I change the zoom of say 50-66% levels. If I change zoom levels to say 100%, the rectangle can become white Uni. The rest of the picture displays normally. Not sure what is the cause. I also once today clicked on a smart object so it would open in camera raw. While I was moving the cursor clarity, all words as temperature, tint, exposure, contrast, highlights and shadows, white, etc. have disappeared but the sliders themselves were still visible and I could move if I wanted to. Very strange! This has happened on several different files. There is nothing wrong with the files. I generally will be just close the files and relaunch photoshop and they will be fine for a while until that the problem popped up again.

    I use cc14 and a wacom intuos 4. I'm on a mac OS10.10.3.

    Use graphics processor to speed up the calculation and use open CL are checked.

    These problems began recently with the completion of the last update on photoshop CC14.

    I had a similar problem last year with menus and images becoming white Uni and don't forget that the cause of this problem was some incompatibility between ps and wacom pens. I remember there was a patch that corrects this problem and I think that I installed last year.

    Help, please.

  • Mozilla site does not display correctly

    I just installed Windows 10 (64 bit) on a new PC and downloaded and installed Firefox. I tried to install some add-ons, but immediately found that the Mozilla Web site did not display correctly: text is displayed, but not graphics.

    I tried the following:
    -disabled the firewall (ESET)
    -deleted the cache and remove all cookies
    -uninstalled Firefox, deleted the user and re-installed Firefox profile
    -a confirmed that "load images" is set to "Allow" on the table in the Page Info permissions for mozilla.org

    I've attached a screenshot of the Network Console, which shows beams with zero file size. This suggests a possible cause of the issue?

    Can you help me with this, please?

    I think that the lock bar icon indicates a problem with connection to the style sheets in mozorg.cdn.mozilla. NET. You get a connection error secure loading one of these stylesheets directly?

    https://mozorg.CDN.Mozilla.NET/media/CSS/home-bundle.063ce4c50b67.CSS

    A sucessful load looks like a wall of text starting with:

    @font-face{font-family:'FA-Icons-Home';src:url("/media/
    

    ESET is a potential suspect in any secure connection because, by default, it intercepts all navigation connections to filter harmful content. However, if the problem is ESET, then you would encounter problems on all secure sites, so ESET might not be the culprit here, if this does not affect other HTTPS connections.

    10 Windows, one of the possible causes of the errors of secure connection are not set up Firefox to work with parental parental control of Microsoft software. More information about this feature: http://windows.microsoft.com/en-us/windows-10/turn-off-microsoft-family-settings

    Is there a broader model? To continue the investigation, you may inspect the certificate on another site that makes it easy, as my test page at: https://jeffersonscher.com/res/jstest.php

    Assuming that you get an error page, expand the section "I understand the risks" and look for a button Add Exception.

    Note: You don't need to complete the process of adding an exception - I suggest not adding one until we know that it is not a malware issue - but you can use the dialog box to display the information that makes Firefox suspicious.

    Click Add exceptions and exception certificate dialog box should open.

    Click on the button display. If the view is not enabled, try first the button get certificate.

    This should display the certificate. Look at the section "issued by" and the Details, the hierarchy of certificates tab. What do you see here? I have attached a screenshot for comparison of screen.

  • Why facebook page now is not displayed correctly?

    Hello. my firefox up to date. My question is, since the afternoon (instead of me) my facebook is not displayed correctly, it something like accident. When I use another browser, its ok. I have also to restart firefox and after I opened facebook again but it still the same. Please help me solve the problem. Thank you.

    What seems wrong?

    Have you checked your plugins?

    Did you already try clear and disable hardware acceleration?

    Try disabling graphics hardware acceleration. As this feature has been added to Firefox, it has gradually improved, but there are still some problems.

    You will have to perhaps restart Firefox for it to take effect, so save any work first (e.g. you compose mail, documents online that you are editing, etc.).

    Then perform the following steps:

    1. Open the Firefox Options (Preferences on Mac or Linux) as follows:

      • In Firefox 29,0 and above, click on the menu button

        then select Options Preferences on Mac or Linux, or Windows.

      • In 28.0 Firefox and earlier versions, click on the Firefox orange upper-left button, then select the 'Options' button or, if there is no button up Firefox, go to tools > Options.
    2. In the window of Firefox Options (or preferences), click on the Advanced tab, and then select general.
    3. You will find in the list of parameters, the checkbox use hardware acceleration when available . Clear this check box.
    4. Now restart Firefox and see if the problems persist.

    In addition, please check the updates for your graphics driver by following the steps in the following knowledge base articles:

  • Japanese language does not display correctly.

    Japanese symbols do not display correctly. On some sites, I see only a long row of squares instead of what is supposed to display. Sites Web appears correctly on Chrome and Internet Explorer.

    My system is in Japanese, and I use Windows Vista. The only program that has problems with the display of the Japanese is Firefox 26. I used Firefox 2.0 before this update, and everything worked well on FF2.0.

    EDIT: Ended up being a user error, looks like I've had a few conflicts of fonts.

    Joint are some screenshots on what it looks like on FF26 (boxes) and Chrome.

  • Satellite A10: LCD does not display correctly

    One of my users has an A10 with a screen problem. The LCD screen is not displayed correctly. You can only see the things on the screen, but they are very very low, essentially unusable. I hooked to an external monitor, which works very well! If someone has had this problem, and if so what was the solution. I incerased brightness etc, but to no avail. Am I missing something very basic?

    Hi Patrick,

    It seems that your FL inverter has failed. It is a component material that offers the backlight to your screen.

    Typical symptoms of failure are that the screen will be visible, but only just, while an external monitor works perfectly.

    I suggest that you only contact a Toshiba authorized service center.

  • Barracuda Spam &amp; Virus Firewall is not displayed correctly.

    Firefox has just updated from 5. < something > to 7.0.1 on my HP Windows 7 64 bit PC.

    Before the upgrade, the Barracuda Spam dialog correctly.

    After the upgrade, the left column where all the boxes are, is now too narrow to display the boxes and watch instead of points. If I have the mouse on where the box is supposed to be, a small pop-up appears and displays the checkbox but I can't go to her because she seems to be a sort of invocation of method of scoring.

    First of all, we noticed this on the computer of my wife which apparently updated 7.0.1 earlier today. Open the same page in IE works fine. Open the same page on my update of the computer pre-Firefox worked fine. After the upgrade, it won't display correctly now.

    No other changes made. The update for Firefox 7.0.1 broke. Needs fixing, needs fixing soon please.

    Thank you.

    I can verify that it is not attached to either 9.0. However, my ISP switched to one just today updated Barracuda Spam and Virus Firewall. It is running Firmware version 5.1.0.013 production and boxes now display correctly.

    Kudos to Barracuda.

  • I just downloaded Firefox 4.01 but it does not display correctly.

    I tried to upgrade Firefox 3.6.7 to Firefox 4.01 but when update is finished, the browser does not display correctly there is for example no address bar. Here is a screenshot: http://i.imgur.com/zBujK.jpg.

    I've downgraded to 3.6.17 and then installed Firefox 4.01 again but this does not solve the problem, or don't leave the browser and entering again or restart the computer.

    Try:

    Start Firefox in Firefox to solve the issues in Safe Mode to check if one of the extensions of the origin of the problem (switch to the DEFAULT theme: Firefox (Tools) > Add-ons > appearance/themes).

    If this does not work in mode without failure, then disable all extensions and then try to find out who is the cause by allowing both the problem reappears.

    • Choose "Disable all add-ons" on issues to troubleshoot Firefox in Safe Mode to set window to disable all extensions.
    • Close and restart Firefox after each change through "file > exit ' (Mac: ' Firefox > leave";) Linux: "file > exit ')
