Hi all . I'm newbie, I having a trouble about VirtualDub. I follow a step by step this guide to: http://www.afterdawn.com/guides/archive/copy_dvd_to_xvid.cfm But when I launch VirtualDub and open the VFAPIConvered file. It show a erro like this: "Couldn't locate decompressor for format 'vifp'(unknown) VirtualDub requires a Video for Windows(VFW) compatible codec to decompress video. DerectShow codecs, such as those used by Windows Media Player, are not suitable." I installed Nimocodac 8 but it don't work too. I also try Klite codec. So, which codec I should use to fix this erro? Thanks so much.
