Hey All:
XP2200 with an MX440 (8xAGP, AGPGART), on an nforce2 motherboard.
I'm running atrpms 2.6.10 kernel which has AGPGART built in and I
don't think I can turn it off ?? and use the NvAGP driver. I also
cannot run RenderAccel, it results in a KDE lockup.
I'm having trouble playing back 720p HDTV and need some suggestions:
SDTV, PVR-250 (720x480), using libmpeg2, no XvMC:
mythfrontend --> 16% processor usage
X --> 9.8% processor usage
SDTV, bttv to MPEG4 (720x480), using libmpeg2, no XvMC:
mythbackend --> 62.8% processor usage
mythfrontend --> 16% processor usage
X --> 9.6% processor usage
HDTV --> HD2000, dvb drivers, 720p source, using libmpeg2, no XvMC
mythfrontend --> 55.1% processor usage
X --> 31.5% processor usage
mythbackend --> 8% processor usage
CPU is pegged, and playback stutters.
WHAT SHOULD I DO TO DIAGNOSE / IMPROVE THIS? Should the X processor
usage be so high for the HDTV stream?
Thanks,
John.
