Forgive me if this question has been posted somewhere else.....I'm new to this forum. Nevertheless, I was hoping that someone may be able to help me out.
I have recorded about 20 minutes of uncompressed AVI video at 640x480 (no codecs applied) that has taken up about 24 GB of hard drive space. This video was recorded on my ATI All-In-Wonder Radeon video card (32 MB Video Memory). When playing back this video I have absolutely no problems. I can play it back in the ATI's File Player, Windows Media Player, Real One Player, etc. However, when I attempt to play this captured video in VirtualDub, the video is slow and choppy. The audio appears to be fine (maybe a little slow) but is naturally out of sync with the choppy video.
Can this be explained or better yet, can it be fixed? Is there some setting or preference I should be checking or paying attention to? Why is playback not as smooth as it is in other commercial players? Is there some sort of limitation that VirtualDub cannot process a certain file size and above?
I would love to cut up and edit this video but I can't do it with this problem.
Any suggestions would be helpful.
Thanks.
Mark V.

VirtualDub isn't a movie player. Just because it can't play the video in real time doesn't mean that you can't still edit and process the video.
It might help the choppy playback to check "Options/Enable DirectDraw acceleration."
Also, I would recommend capturing with the lossless Huffyuv codec in the future; you'll save a lot of disk space without losing any quality. (Even more savings if you set your video format to YUY2.)

Thanks fccHandler! Your suggestion of enabling DirectDraw acceleration did the trick.
Thanks for your help!
