Thanks for the responses. My biggest question is whether or not it is normal for the X process to be taking 30% processor time and mythfrontend 55% processor time when performing 720p playback.
I viewed with interest Jarod's posts over the past week or two and it seems that he's getting solid HDTV (1080i) playback on an XP2600 without XvMC. http://www.gossamer-threads.com/lists/mythtv/users/122884?search_string=HDTV%20Playback;#122884 I'm wondering if I have X, myth, or somthing misconfigured. If Jarod is right on (usually is), I should be able to playback 720p without any trouble on an XP2200, no XvMC. When frontend opens, I see a line like "Using XV on port 108" or somthing, so I'm assuming that xv is being used. What else do I check? Thanks, John. **************************** Orig. Post: 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.
