I have seen a couple of threads here that have asked about this particular error: "Couldn't locate a decompressor for format 'dvsd' (unknown). VirtualDub requires a Video for Windows (VFW) compatible codec to decompress video." The only response to this question was to locate g-spot in the software section and download it. Well, since it WAS named g-spot, of course it was impossible to find. Could someone help me with exactly what is needed for Virtual Dub to read this .avi file (created by VFAPI) correctly? I'm following the exact directions in the afterdawn dvd - divx instructions, and this is my first hitch. Please help!
