I can playback 720p(65% cpu load)/1080i(95% cpu load) using XV(libmpeg2) just fine on an athlon xp 2500+ (geforce4 mx440/nforce2/kernel 2.6.13) based system. However when using XVMC I could playback 1080i(50% cpu load) smoothly but 720p(30% cpu load) content would start stuttering after an initial pause or skip. Initially I was using the onboard audio chipset (alsa intel8x0). After Daniel's suggestion I tried a different sound card (alsa ice1724) but it still occured. I also tried with and without the chromakey osd enabled and noticed no difference. Then I switched on the "Use Video as Timebase" option and turned off AC3 passthrough and the 720p/xvmc playback problem went away for me. However 1080i video seemed a little less smooth but with good audio. The reason I disabled using video as timebase was due to an issue using it and AC3 passthrough together. Using both of these options caused only a few bleeps of sound every second or so to be processed on my receiver yet the video played back smoothly. This happened on either sound chipset I used too. Anyone else having an issue using both? It would be great to be able to have AC3 passthrough and "Use Video as Timebase" work together since using video as timebase seems to provide smoother video. Anyways just thought I'd pass along what I'm seeing. Let me know if I can provide anymore information. Thanks. -- Taylor __________________________________ Yahoo!
