You'll find that it takes atleast 1gig of ram to render much more than 10 minutes of video. You'll also want to make sure all other programs are closed, or restart the computer when you use pinnacle, and never even think of doing anything else while burning. Another Problem is Pinnacle. They offer a decent product with poor support. I've finally had it with Pinnacle and am switching to Adobe. So Lotsa Ram; no other programs running; make sure screen savers and the like are turned off; and atleast say a 2.2 P4 processor. Let me know a little more about which updates you have and your computer and I might be able to help more.
