I enabled HPET on my system yesterday, verified it is on using WinTimerTester 1.1. Removed advancedsettings.xml to run without delay. Sadly it does not make a difference.
While testing I discovered another thing: If I rewind and ffwd a couple of times the missed: counter stops incerementing. I can see this in CodecInfo ("o" key). When the missed counter stops the a/v value stabilizes some, and does not fluctuate as wildly, and as a result the lip sync is more consistent. a/v value is not as stable as in 50Hz, but it is an improvement.
Also, as many others have said in this thread, if I disable vsync, lip-sync is perfect, but ofcourse not a real solution due to visible tearing.
