Don't let the name mislead you. Sure, motion compensation was probably the initial motivation, but my understanding from reading posts about it on Xpert (Mark or someone please correct me if I'm wrong) is that it supports non-MC surfaces, so it's basically a beefed up Xv which supports MC and direct rendering. -- Earthling Michel Dänzer (MrCooper)/ Debian GNU/Linux (powerpc) developer XFree86 and DRI project member / CS student, Free Software enthusiast _______________________________________________ Xpert mailing list [EMAIL PROTECTED] http://XFree86.Org/mailman/listinfo/xpert
