I had a curious issue w/ my HTPC. I was running an 800EB on an Asus TUSL2-C mobo. HDD is a Quantum 4GB ATA66/5400rpm while sound card is Philips AE and vid card is Radeon 64MB VIVO; DVD drive is Toshiba 1502. FPTV is an Electrohome ECP400. Resolution for DVD playback w/ PowerDVD 3.0 is 1024*768*32 under 98SE. W/ the 800 P3, I had a flicker in the video image at random moments when playing some DVDs. I am at a loss to explain this. To fix the problem, I inserted the TUSL2-C mobo and CPU from my regular computer back into the HTPC in place of the 800EB and the TUSL2-C mobo it is on; the flickering is now gone. The 800EB is now running @ 929 (155FSB) in my regular PC w/ no problems. Anybody have any idea why this would happen? I was always under the impression that an 800 MHz CPU was more than enough for software DVD playback.
