I've come across a frame-accurate mpeg4/avi editing tool that I'd like to share with all VideoReDoers. It's called avidemux ( http://fixounet.free.fr/avidemux/ ). It's freeware and handles all mpeg4 streams (as well as opening and converting to mpeg2). As with VDub, it doesn't install, it just unzips to it's own folder. If you're just cutting stuff out (adverts etc.) and saving to the same format it will only re-encode the frames around the cut-points (like VRD), so is pretty quick. It has a whole array of filters when you are re-encoding and I can't believe it hasn't been mentioned or discussed before; I only stumbled across it in a thread on the AfterDawn forums.
