trouble importing avi's on DVD-Roms

I have been given 4 dvd roms to extract footage from and to piece together for output to DVD-Rom again.
The problem is that most of the discs will not load. A pop up wit coorupted file or unknown format comes up.
When I try to play the disc in WMP the footage is very jerky and the audio is totally intermittant.
Has anyone got any ideas on how to get around this problem-is it possible?.

Sounds like you need to extract the video first from the DVD and then convert it if necessary.

If it is a DVD with video, then the video has the extension of VOB. It is an MPEG2 file, but has several different audio layers mixed in. YOu need to use software to Demux the audio, then you can import the video as an MPEG file.

The stuff on the dvd is an AVI file. But when I try to import it either says the file is corrupt or is an unknown format.
I opened the avi to play in WMP but it was very bad, kept sticking, and very intermittant audio playback.
Could this be that the disc is corrupt or do I need to set up my WMP to play the file?

Get into Windows Explorer and navigate to one of the AVI files on the DVD. Right click on the file and select "Properties." Under the "Summary" tab see what it says is the video compressor. (This is for Win2k, I don't remember what Win98 calls the "Summary" tab but it's in there.)

An AVI file is merely a container and the file can contain video compressed with a variety of codecs. If the summary says "unknown compressor" (or something to that effect) then you don't have the correct codec installed on your machine. There are ways to figure out what codec was used, but Windows won't tell you without help from some program that tells you the "FourCC" code imbeded in the file. Then, there are a couple of web sites that will tell you what FourCC code corresponds to what codec. Unfortunately, I don't have access to the URL's at the moment, so you'll have to Google it.
