I have spent the last twenty minutes reading articles, trying to find someone with the same problem that I do. I was able to find similar posts, but I could not be sure that their issues were the same as mine. I apologize in advance if this has been posted in the past, but I am not an experienced user and some of the possible matches were hard to understand at times.
THE PROBLEM:
Several times during VLC's playback of an .avi file (this has occurred in versions 0.98, 0.99 & 1.0), the audio and video will pause for a fraction of a second, then the audio will continue and the video will stick for about 2-4 seconds. After that time, the video becomes boxy and eventually changes into what it should be. It does not catch up if I pause it, but if I rewind the video, it does not happen in the same spot. This happens when I am merely playing back an .avi file and nothing else, and it also happens when I open files or applications.
I am using a 17" MacBook Pro 2.67 GHz Intel Core 2 Duo w/ 4GB 667 MHz DDR2 SDRAM. I have a GeForce 8600M GT with 512 MB of VRAM.
