Any of you familiar with Sony Vegas 9.0?

Working on a video of some game footage, and I’m having trouble with Sony Vegas 9.0.

I’ve got everything all edited up, sound set, etc. Problem is, every time I try to render the video I just get a black screen. The audio works fine, but the video is completely black.

I’ve tried rendering it in several different configurations using Xvid, and even tried to render it out completely uncompressed so I could try compressing it using VirtualDub. Still no luck :(

I’ve Googled around and I’m not having any luck finding solutions for this with 9.0. Why is Vegas such a pain in the ass to use? :(

If someone could save all my hard work from going to waste on this, I’d be really grateful! :)
