When I try to open the movie file I have. The VirtualDub gives me this error...........Couldn't locate decompressor for format 'MP42' (Microsoft High-Speed MPEG-4 V2). VirtualDub requires a Video for Windows (VFW) compatible codec to decompress video................. This what happens when I try to covert the audio to wave. I can watch the movie in my windows media player so I have the right codec to watch it. The movie is a AVI file. So if anyone could help me I'll really appreciate it thx......
