Media Player Classic HC VMR9 question

[THX-UltraII]

Strugling with lipsync problems for months now. Yesterday was a breakthrough! I finally found out something which you guys maybe can help with:

When I disable the d3d (remove tearing) option I get NO LIPSYNC problems. When I enable it I get lipsync troubles from the very beginning of a movie. Lock-back-buffer doesn t help.

So, probably you think: Why not keep d3d disabled? Because I can t. I HAVE to use this feature in to get 100% tearing-free playback. Haali is also no option: in Haali the tearing is less than with VMR9 but still present.

So the conclusion is that with VMR9 renderless d3d something goes wrong.

I've never had a problem with it.

Grabbing at straws here...
Do you have a dual core AMD CPU and Windows XP installed?

AMD Dual-Core Optimizer Version 1.1.4 - The AMD Dual-Core Optimizer can help improve some PC gaming video performance by compensating for those applications that bypass the Windows API for timing by directly using the RDTSC (Read Time Stamp Counter) instruction. Applications that rely on RDTSC do not benefit from the logic in the operating system to properly account for the affect of power management mechanisms on the rate at which a processor core's Time Stamp Counter (TSC) is incremented. The AMD Dual-Core Optimizer helps to correct the resulting video performance effects or other incorrect timing effects that these applications may experience on dual-core processor systems, by periodically adjusting the core time-stamp-counters, so that they are synchronized.
