How to fix Gen6IntelGVAQueryAVDCommandStatus timeout?

Question

When playing video files, typically m4v type files, using QuickTime, iTunes or VLC and maybe other players, the video freezes for 30 seconds or so while the audio continues.  Then the video plays rapidly until it catches back up with the audio.  When this occurs the console logged this message:
Apr 30 16:42:02 Marks-MacBook-Pro /Applications/QuickTime Player.app/Contents/MacOS/QuickTime Player[9339]: AVF error: Gen6IntelGVAQueryAVDCommandStatus, TimeOut. Resetting.
Does anyone know how to fix this problem?
The Macbook Pro is a 2GHz early 2011 with 8GB of RAM and a SSD.  Additional processes have been reduced to a minimum and Activity Monitor indicates that the computer is just loafing along when this happens.  The problem occurs when streaming from a local server and when the file is on the Macbook Pro.

I am also very interested in an answer to this question. In my case, I was watching a 1 hour m4v file on QuickTime Player 10, when about 25 minutes into it, the audio kept going but I couldn't access the window controls. After a few minutes of this, I force quit QuickTime Player, but everything else had hung as well. I couldn't quit other apps or click anywhere, so after a few minutes was forced into a hard restart. Not happy, since my MacBook Pro 17 inch early 2011 is a replacement after a faulty drive messed up the first one too many times. It has 8 GB ofRAM and a 750 GB 5200 rpm hard disk. The computer was not being pushed very hard when this happened. The m4v file is locally stored and is only about 153 MB.
The console message that began the long string of trouble was the following:
