Interestingly, mine seems to be having a little trouble as well. As way of history, I intended to use XvMC, but I can't, because of the "Prebuffering" issue, which eats CVS myth for lunch.
Frontend1 is a Mobile Barton 2400, 200mhz FSB, 1800mhz clock, PC3200, NV 5200ultra AGP, FC3 2.6.10-DVB kernel. Currently using 960x540p output. Frontend is currently set for deinterlace, BOB, using Libmpeg2. I have (3) HD recordings on my backend right now, and here's how they play. 2092 - NBC, Tonight Show, 1920x1080x29fps - plays smooth, loses audio or locks if you skip ahead or behind. Plays beginning to end just fine if you let it. VIDEO: MPEG2 1920x1080 (aspect 3) 29.970 fps 18906.0 kbps (2363.2 kbyte/s) 2094 - ABC, Boston Legal, 1280x720x59fps - choppy chunky CPU can't keep up. VIDEO: MPEG2 1280x720 (aspect 3) 59.940 fps 45000.0 kbps (5625.0 kbyte/s) 2081 - CBS, CSI, 1920x1080x29fps - plays fine, CPU at 99% however. VIDEO: MPEG2 1920x1080 (aspect 3) 29.970 fps 45000.0 kbps (5625.0 kbyte/s) looking at this, I think it's just CPU. I have some room to clock the CPU up.. I've had it undervolted and underclocked to try to keep the heat and noise down, but I may not have any choice. > Dohh I was a little bit late.
