Ok, so I just got a TV tuner card for my PC, and am planning on using the thing to record some shows. Problem is, the file sizes tend to be a lot larger than I'd like. So, I'm trying to use VirtualDub to covert the MPEG-1 files that the recorder program produces into XVid files... except that the result is that the XVid file is bigger than the original. What gives? Can anyone help? Or do I have no idea what the fuck I'm doing? (Probably.)
