[QUOTE="Pat Clark, post: 934526, member: 123421"] Here's what I see: 1080i signal (Stall shown as 14ms for all cases, I think, but I forgot to check each case. I assume this is a fixed value for 1080i.) [code]Without MPAR: Aero on, 32-bit PC monitor. Buffering: off, 23-25ms unstable, many drops, video unacceptable. Buffering: 7, 17.5-19.5ms unstable, many drops reported, video OK Aero off, 16-bit PC monitor. Buffering: off, 13.5ms flat, no drops (This is a surprise result here. Some other change must be helping.) Buffering: 7, 13.5ms flat, no drops (This is how I have been running.) [/code] Enabling MPAR caused a near collapse of MP. CPU up to 80%. Video stalled completely from time to time, with pixelation, sound problems, etc. Otherwise, the setup was the last one above. I then tried a more standard MPAR setup: Aero, no buffering, 32-bit monitor (required). 17.5-19ms render, unstable, some drops reported, video OK but "off" somehow. Can't say what was wrong -- it wasn't jerky, but seemed wrong. Program being watched wasn't very active, so hard to tell. That's all I checked for MPAR. [/QUOTE]
