I am trying to follow the guide here on Afterdawn to join 2 AVI files together using Virtualdub. When I attempt to open a file, I get the message saying that it can't find a suitable VFW decompressor. The only codecs I have installed are FFDShow and some OGM and OGG codecs. I have not installed any codec packs because FFDShow was all I needed to view any file using WMP10. So how do I get a VFW for Virtualdub so I can work with all types of DivX and XViD files? Thanks.
