sounds good but can't you just do an avi with shoutcast of both of them? would be less work as well i guess. Or is it supposed to be some kind of promotional video?
hehe ok i thought you wanted to take scenes from both finals and combine them in one video. Good luck ,hope it turns out to be good. If you have a 2nd computer you could try to record the signal of the one that is playing the demo instead of working with q4's avidemo function.
Thats not an issue, this PC could run 4 Quake 4's and still not slow down. The issue is with the demo playback function built into Q4, its simply jerky all the time and nothing I change makes the slightest bit of difference.
