Also note that it states no de-interlacing is being used. So yeah, I would say it's hopeless to get HD happening on that processor without XvMC. AGP/PCI should make no difference that I can tell. The table also states that using a Pentium 4 2.4, you can run HD without XvMC and get up to 70% CPU utilization. Switching might be your best option. You'll have to check your processors to see if they use the same socket. Pentium and Celeron came in a variety of different footprints. </FONT></FONT></DIV></DIV></BLOCKQUOTE><DIV><BR>Interestingly, I've gotten XvMC working (in the sense that I get the gray OSD).

I shudder to think what my wife will say if I tell her I need to buy a new P4 just to play back the HD.
