I am trying to convert an AVI file to a DVD-R - I am using the guide that is found on this site but my movie is split into 2 main AVI files - In the guide it says to use Virtualdub but when i try to do that, virtualdub says" Couldn't locate decompressor for format 'MP43' (Microsoft High-S[eed MPEG-4 V3) VirtualDub requires a video for windows (VFW) compatible codec to decompress video, directshow codecs, such as those used by windows media player, are not suitable." What does this mean? Can i just use AVICodec to do both at the same time?
