If you have a reasonably fast system (1.2 GB) or faster you shouldn't have any problem if you have one of the newer second generation burners. A dual processor won't help anything for burning AFAIK but maybe the rendering process and then only marginally. To be extra safe turn off all TSR's, anything that could jump up on its own like screen savers, anti-virus. The problem with dropped frames has nothing to do with the burning process. I suspose buffer underrun could be a problem if you have a older DVD burner, but if you got a newer one that's a issue from the past too. The best thing not to do... DON'T go crazy with the bitrate! The default settings should work fine 99.9% of the time. Aside from that about the only other bad thing that could happen is that DVD-A burps with your particular burner, or that your DVD player doesn't like a particular brand of media.
