Fixing Bad frames

[Locutus1979]

I have a movie that plays fine in Windows Media player but when I open it up in Virtual Dub and scan for error it finds 1 bad frame and 38 good but undecodable. How can Media Player play this without any problems but Virtual Dub is telling me there are errors. Seeing as I can play it in Media player I've tried to screen capture frame by frame for that small section that Virtual dub says has erros but when I paste it in Adobe photoshop it is behaving rather strangley. If I capture the whole screen and then try to crop it down the movie frame moves (I can't figure it out. It even does this when I use Snagit) I don't really care if I have to delete that 1 frame but I'm having a hard time understanding why Media Player can play it without problems.

Any suggestions? Do I keep trying to capture frame by frame like what I've been doing but with another program? I've also tried to capture video using Snagit but it is really slow. The sound will be at normal speed but the frame rate is really lagging. I've got a decent computer and memory (AMD 1800 with 64 mb ram Video Card and 1GB of DDR RAM). All I need it to capture a few seconds of video. Any suggestions would be greatly appreciated, Thanks

After scanning for bad frames set both audio and video to direct stream copy then save avi. The bad and undecodable frames will be removed in the resulting saved file.

Playing programs will skip over the bad frames but encoders will choke on them giving all kinds of problems.
