I'm having trouble trying to play a .avi file in QuickTime. When I try to play it QT will not open it, and just gives the error that "QuickTime cannot open ....avi because the end of file was reached prematurely." I have the latest versions of divx and 3vix plug-ins installed, and other similar .avi files play fine in quicktime. If I try to open this file in VLC, it will play for about 40 seconds and then VLC will either unexpectedly quit, or give an error message about access. Any ideas?
