On the box I used until recently, compiling in XVMC support helped enough to make *some* HDTV programs watchable. Most shows still stuttered. The box had an Athlon 64 3200+ and a GeForce 6200. SDTV and analog worked very well. As a workaround, I set MythTV to transcode all HDTV programs automatically to a lower resolution. The transcoding takes a long time, but the real problem with that solution is that when the signal fades, the transcoder isn't very forgiving and drops a lot of the recording. FWIW, the new 5200+ CPU with a GeForce 7300 plays and scales HDTV in real time with only 30% CPU utilization, meaning approximately 60% of 1 core is in use. Interestingly, XVMC doesn't reduce the utilization. Shane /* PLUG: http://plug.org, #utah on irc.freenode.net Unsubscribe: http://plug.org/mailman/options/plug Don't fear the penguin. */
