i7 / Win7-64 / Nvidia GTX660M laptop - losing 1-3 frames every several seconds playing back any video tested; WMV, H246, AVC, etc.. No symptoms on my other PCs, so it seems to be unique to this laptop's ecosystem. I've looked for I/O bottlenecks and other obvious issues but can't find anything, and other video players are working as expected.
I've read mentions on other threads to log files, and there are mentions in the log to issues:
main debug: picture might be displayed late (missing 8 ms)

Any thoughts on how I can debug this?
