Hmmm I've always used Divx, but only as a media player that plays .dvd files, and that's only on boring Mondays and all I can do is sit and watch reruns of Love Hina. It's never given me any problems with compression. As for Bryce 6, I think we're all as mystified as you are. Claiming to have faster render speeds on the next version is a Bryce trademark.
