How to fix audio and video?
Yes while watching a video (whether on Youtube, etc.) or a downloaded in Quicktime video format will stop after a minute and the buffer or simply freeze (Note: though it has already loaded or is already on my hard drive!), will be so audio. After 15 seconds the sound plays and the video remains frozen.
Same thing while listening to music (Spotify or Itunes (both downloaded)), the music will stop randomly. After a few seconds, the music will continue with a whistling noise that fades in 5 seconds approximately.
It started a month ago, and since then, I have tried several things:
Reinstallation of Flash
Update of Flash and any other update like OSx
My mac to a timemachine image backup
tried several different browsers
tried several different wireless LANs (although Itunes etc. do not need those)
has ran a Virus Scan
Nothing has done so far. I don't know what to try anymore.
So my question is:
This who can I try to fix this? How can I go to find out if it is a hardware problem? Could a factory reset fix, and not not not using a backup, but simply install new OSX?

Qosmio F10: How to record audio and video and use QosmioPlayer
I am owner of a Qosmio F10-122 with TV tuner and I really need HELP. I'm Italian.
The questions are:
1 QosmioPlayer version 4.0.1 (2005022812) (according to the procedure of the forum) has installed fine but the sensitivity is poor; in any case the question is: is is possible to record videos? Also is it possible to record audio?2 input and video output are stupid; I can see Windows and QosmioTV on HDTV via DVI/SCART but I can't input in MCE TV or QosmioPlayer any signal IN Composite; so the question is once again how can record AUDIO from my Home stereo or VCR VHS VIDEO?
3. I only use VIDEO IN to WATCH is not to save: where is my fault?
Thanks, Marco
Hello Marco
I did some testing and I can tell you about my experience on Qosmio G20.
1. as far as I know early versions of Qosmioplayer did not have the registration option but now I hope that your preinstalled version has REC option. If so, please be sure that you have about 5 GB of free space for the recorded material.
It is not important what signal is sent to your Qosmio (TV or VCR VHS-connected) you can find it if you look at the channels. With REC option, you can save what you want. I tested it with my VCR VHS and I recorded some old movies. This material was recorder und great quality was the same as on cassettes. After recording, I started Windows MCE and transferred the material recorded in Windows using Qosmio player utility.
I have not tried, but I put t think you will be able to record audio using only Qosmioplayer.
2. you can record movies VHS if you connect your VCR VHS on the Qosmio using the antenna cable. Launch Media center Edition (TV option) and scan channels. In my case, I could watch movies VHS on MCE on channel 31. Using REC option you can save all documents of video cassettes. Later, you can change the recorded material and create own DVDs. It really isn't a problem.Your audio Home Audio recording can be a bit more problematic, and if you want it to be on the professional path you will need a device external and of course some professional recording software.
3. I don't know what to write here. Just try to do what I already descriebed under 1 and 2.Good bye

If I remember OK, in first previos versions, it was possible to drag multiple Clips in the project area to the timelineand apply automatically audio/video transitions.
It is possible to configure how many video images will overlap to a default value of transitions (and for audio, too).
Is this possible in first CS6 to do the same thing? Leave me a link to the documentation or a hint, how to get this thing done.
I searched the documentation, but I have not found.
Thanks for the tips.
I believe that the function you are referring is automate to sequence. In CS6, it is in the project Menu. for those who use the CC, it's in the Clip Menu.

How can I me audio and video synchronized?
I use first 13 with Windows 8.1 items to change the old VCR tapes that I transferred to my computer with WinTV. Everything seemed to work - until the middle of the edition of the band, the audio is 8 seconds behind the video. I checked the original in my computer that I added to first Elements and audio and video are synchronized, but in the middle of editing, they are out of sync. There is no way to cut off the part of the video without also carve out part of the audio now synchronized. No way have to slide forward only audio. I tried to delete the new part of the original in Premiere Elements and then adding back all original and cutting of part I had already edited but audio-video synchronization is still off. Any ideas?

First 13 items on Windows 8.1 (supposed 64bits).
If you have not already the case, update 13-13.1, using Help Menu/implementation of an open project.
First of all ensure that you (manually) or project (automatically) set preset to match the properties of your
source file. See Edit Project Menu/Settings/general and the readings for the Mode of time base edition, image size and Pixel Aspect
Ratio (even if the fields search grayed). If your source is VCR tapes, I am projecting that you deal with Standard 4:3 which would point
to make the project preset according to your predefined project DV Standard NTSC or PAL DV Standard configuration.
Reading the script contained in the monitor of the editing area, you should look at and listen to the content timeline made (i.e. no color
line on content or a green line). Is this the case?
A manoeuvre to deal with this kind of situation (if alternatives are missing).
a. unlink video and audio.
(b) you hold ALT on the main keyboard to the computer, press the arrow key left or right. A single tap = 1 help from frame. Or, as
you hold it the main computer keyboard Shift + Alt keys, press the left or right arrow key. A single tap is 5 frames progressive jackpot.
Please read and review, and so let me know if I have targeted your question. If not or need clarification, please do not
not hesitate to tell me.
Thank you.

Somehow, I have disabled the feature that allows to drag and draw audio and video tracks on the timeline to other titles or positions of import. Is the only project that was hit, and everything that I can think is that when executing some other keyboard shortcuts, I accidentally performed a shortcut that turned this feature off.
You want to say, "Snap"? Press "on the keyboard, or press the snap button in the timeline panel.
