WMP can play some mp4 files, impossible to read some, how do I solve this problem?

I use WMP version 12.0.7600.16667.

It can play mp4 files (so must have installed the codec requirred file), but cannot be played some I downloaded from youtube.

How can I fix it?

Help, please.


In general, MP4 is just a file extension, and the codec used for encoding defines the format.

But as you say it is downloaded from YouTube, the issue isn't with the WMP (or any other player). If you use Internet Download Manager or YouTube Downloader or any other software, the problem occurs. This is due to changes made by YouTube in their Web site. Update the version of the software was found to solve the problem.

    Just some thoughts...

    It may be useful if you are going to... Tools / Options / Compatibility tab...
    and uncheck all filters.

    Also... it might be a compatibility problem with your source files...
    (videos / photos / music files)

    Several formats are apparently compatible with
    Movie Maker, but the most reliable choices are:

    Photos - bmp
    Video - wmv or dv - avi
    Music - wma, wav, wmv

    Also... If it is a large complex project, you could have a system
    the question of resources. The answer would be to create

  • I try to download an MP4 file in FCPX and get this message "no Importable none of the selected files or folders can be imported." "Changing the selection and try again" does that mean and how do I solve this problem?

    I get the "No importable files" message when I try to download a webinar for editing mp4 file. I have try the MOV file and still no change.

    IS the file on the computer? Are you using the FCP import window? You can open the file in QuickTime format? If you can't that means the Inspector's report?


  • my windows media player won't let me play movies or download them.i cannot find a way to solve this problem.

    I use vista home 64.eu if I try to use another media player you need on my entire system. I hope someone can help me.thanks.

    Hi Kathy,

    What happens when you try to play or download them? Nothing at all? You get an error message? If what makes say exactly Word for word including all codes? What version of WMP are you using?

    Despite your comment about other media players "support for the entire system" (what means exactly what it means and what other media players are helps you - names and versions)?, I would suggest you download and try free VLC Media Player: http://vlc-media-player.en.softonic.com/.  He helped a lot of people with problems WMP.

    If it does not or you do not want to use a different media player, so you know when this problem started?  Try a system restore to a point in time BEFORE the problem started.  Here is the procedure: http://www.vistax64.com/tutorials/76905-system-restore-how.html.  Don't forget to check the box to show more than 5 days of restore points.  If the first attempt fails, then try an earlier point or two.  NOTE: You will need to re - install any software and updates that you have installed between now and the restore point, but you can use Windows Update for updates.

    I hope this helps.

    Good luck!

    Hey there dubstepspacecatjr,

    Welcome to the communities of Apple Support! From the sound of things, you experience problems connecting to the internet in specific applications on your iPod touch, such as YouTube and Instagram. You also tried to reset the network settings and reinstall applications, which are key steps in troubleshooting. I can certainly understand the importance of being able to access the internet in order to get most of these applications. I'll be happy to take a look at it with you.

    The first place wherever I would like to first of all is the use of this article:

    If your iPhone, iPad or iPod touch connects to a Wi - Fi network


    If you haven't already done so, good insulation should see if this connection within these apps problem persists when you use cellular data. In addition, check that you are able to browse and connect to Safari on your iPod.

    In addition, you do not want to look at the backup and restore of your iPod as a new device. From there, you can reinstall the applications and see if the same thing happens. This will help to rule out existing issues/corruption of software.

    The following items have the steps on how to create a backup in progress, but also to restore your device to factory settings:

    How to back up your device using iCloud or iTunes


    How to clear your iOS device and then set up as a new device or restore from backups

  • Windows Media Player will not play the .mp4 files after installation IE10 - BEX error message

    Hello! Recently, when I tried to read a file .mp4 on Windows Media Player, the player would immediately stop working and tell me that he could not play this type of file, even if the day before he could do so without any problem.

    Back to a system restore point previous fixed the problem and I could again play the files in Media Player, but during the night that Windows updates installed and the morning I could not play these .mp4 files once more. So I restored to a point earlier, changed my updates so that they are is more automatic and by installing each day at a time, I finally isolated the problem in Internet Explorer 10. If I install that, just Windows Media Player will not play these files.
    I tried a manual update of Internet Explorer 10, turn off all the options of toolbars shit and everything, thinking that when it automatically installs those who may be included, but that has not helped. Had to go back to my previous IE10 restore point. So no matter what, Internet Explorer 10 kills my ability to play .mp4 on Windows Media Player files.
    I don't have toolbars running on IE9 at all.
    I know that's obvious answer is 'do not install Internet Explorer 10' or if I do, download another player for .mp4 files. But the fact is, it shouldn't happen, it is indicative of something being wrong, and I would like TO be able to install Internet Explorer 10 AND use Windows Media Player to play these files. If someone else has had this problem, or know a way to fix it?
    Here are my system specs:
    Windows 7 Ultimate 64 bit
    Intel Core i5 - 3350P @ 3.10 GHz CPU
    ASRock H77M LGA 1155 motherboard
    8 GB DDR3 240 - Pin SD RAM
    Diamond Radeon HD 7870PE52GV 7870 GHz video card
    And all my programs are installed on this:
    SAMSUNG series Pro 840 MZ-7PD256BW 2.5 "256GB SATA III MLC internal Solid State Drive
    I'd appreciate any help you can provide! Thank you!!
    It sounds like your question. I think you should uninstall this update and
    hide and see if that solves your problem. Please report.

    I tried myself after experiencing the same problem and error code. I uninstalled the KB2670838 update, and then my Windows Media Player finally worked again. I also found that IE 10 must be uninstalled as well. Installation of IE 10 also automatically installs the update of KB2670838 platform. After uninstalling KB2670838, IE 10 automatically uninstall with it, better you hide two updates so that they do not install again. From the link in the previous post, I learned that the platform update is having problems of conflict with the AMD drivers. Good luck to you and hope this helps.

    Looks like you are trying to backup either iCloud or iTunes, but you have found an error on files being unavailable. Can reply you with the exact wording or a screenshot of the message you are getting?

    If it doesn't, try a startup repair and / or a system restore using a DVD of Vista from Microsoft

    Manufacturers recovery disks normally do not have Service Options; they are normally a relocation to the factory only settings option.

    Here is the guide to repair Options using a Vista DVD from Microsoft.

    If a friend or a work acquantance of yours has one, you can borrow and use it for repairs.

    4. Conclusion

    If you do not or can not borrow a Microsoft DVD there is a download of a file ISO of Vista Startup Repair available that you can put on a Bootable floppy to make the above startup repair and that the method is recommended by a large number of posters in these Forums.

    Unfortunately, you have to buy it.

    Here is a link to it:



    There are several methods to reinstall Vista.

    This can help you (download files and make your own DVDs):


    And here are instructions on how to burn ISO disk images:


    The download links and information on how to make the ISO file, and then create the Setup DVD above are at this link:

    "How to download a Vista ISO and create a Setup DVD or USB"


    "How to create a USB of Vista Installation key '



    You can contact your computer manufacturer and ask them to send you a set of recovery disks.

    They should do this for a small fee.

    To reinstall Vista using their recovery disk/s, you start from the 1st recovery disk they provide and follow the manufacturer's instructions to reinstall:

    You need to change the Boot order to make the DVD/CD drive 1st in the boot order:

    The recovery process can be started by pressing a particular combination of the key or keys at startup. (Power on / start)

    Maybe it's F10, F11, Alt + F10, etc., depending on the manufacturer.

    Them or us ask the right sequence of key.


    Some manufacturers have more available Vista recovery disks.

    If this happens, you may need to try this instead:

    You can also borrow and use a Microsoft Vista DVD, which contains the files for the different editions of Vista (Home Basic, Home Premium, Business and Ultimate) must be installed. The product key on your computer / Laptop box determines what Edition is installed.

    Other manufacturers recovery DVDs are should not be used for this purpose.

    And you need to know the version of 'bit' for Vista, as 32-bit and 64-bit editions come on different DVDs

    Here's how to do a clean install of Vista using a DVD of Vista from Microsoft:

    "How to do a clean install and configure with a full Version of Vista '


    And once the operating system is installed, go to your computer manufacturer's website and get the latest drivers for your particular model or laptop computer.

    And phone Activation may be necessary when you use the above installation method.
