Anyone else noticed odd behavior playing MPEG on this motherboard?
Clips that should play back at 30FPS, that do play back at very very near 30FPS on any other system, play back at ~ 32.6 FPS. It's a bit like watching Alvin and the Chipmonks.
Environment: Win98SE, WMP 6.4, SIS 2.06 "Full Package" drivers, NTSC TV Output Mirrored to VGA, 640x480 and 800x600.
There are a few hidden video (display) controls, can be enabled from the following registry key, but none corrected the FPS problem: [HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Class\Display]
I'm wondering if it has something to do with how the SIS drivers "cheat"... that is, when the video can't play as fast as the application demands, it will only draw the frame counter, not the frame itself (for lack of a more technical way of putting it), yielding false frame counts. It does a good job of fooling some benchamark programs (ie 3DMark99 Max, haven't tried any others myself), but gives itself away when i heavily load the system, see the Media Player showing near 30FPS but the video frame isn't changing more than a couple FPS with high-res Divx clips.
Update: It seems to be a problem with the v2.06 Full Package Driver or related Settings changes, the original driver (believe it was the one on the included CD) doesn't seem to have the framerate problem, and after installing 2.06 Full Package the problem appeared, but after reverting registry back to pre-"full Package" the problem disappeared, but new driver files/version where still being used. Only other possiblity I see is a relation to the TV-Out, as that isn't working without the "Full Package" registry changes.
