I'm sitting here checking through some AVIs for errors and I realized I have literally hundreds left to check . Since I'd rather not sit at the computer and tell Virtualdub to scan each videostream one at a time, is there some program that can scan a whole set of files in a row? Also, VirtualDub simply dissapears on me when I scan certain files (I don't think it's related to the "Internal Error MMX state left on..." error), any ideas? thanks.
