I'm not a computer geek but after some code chasing I found the reason why VirtualDub (and any other video compression engine, I suppose) could not find its video codecs. I am sending a patch that worked fine for me. I simply noticed the problem is in msvideo_main.c, function ICInfo, which is used to enumerate the installed codecs. The main loop in that function is going through the codecs listed in the System.ini file under drivers32 section. The problem is that the list returned by GetPrivateProfile show only the keys and not the expected key=value pairs. To fix that I simply removed the checking for an equal sign. Moreover, I noticed that it would stop enumerating at the first codec that failed to open. I found better to keep going down the list and just ignore the faulty codec, since I presume that is what Windows would do. Well there you are.
Enjoy,
Waldeck
