Ok, my problem is that I am trying to multiplex the video (divx) and audio (wav) in Virtual Dub on my new machine, and it gets to about 10% and just stops working. VirtualDub is still clocking up time, but no longer processes anything. VirtualDub happily encodes my d2v files to divx on this machine, and is only giving me trouble when I try to combine the streams. No what really confuses me, is that this never happened on my old (slower) machine, and I'm using exactly the same version of VirtualDub, installed from the same CD. I'd really appreciate any light anyone can shed on this for me.
