Hi,
do you have an idea, why there is some VC1 content that plays just fine, but also some, that lags and where the audio drifts after a couple of minutes?
This one is mediainfo for a normal working one:
ID : 1
Format : VC-1
Format profile : Advanced@L3
Codec ID : V_MS/VFW/FOURCC / WVC1
Codec ID/Hint : Microsoft

And the following one there the movie starts stuttering, only plays normal speed after I fast forwarded once. THen after a couple of minutes audio starts to drift. Can be fixed with fast forward/backward again, but starts drifting again:

Can you already spot an issue from the mediainfo and codec or do you need a debug log for both playbacks or video sample files?
