VC-1 decoding stutters.

I have some videos in VC-1 codec with 25fps and interlaced. These have a hard time stutter with Q10 Pro.  Some reported back, that with previous FW (2.0.6) it seems OK, but for me with OFW 2.1.1 it's just unwatchable. I can provide a sample if necessary.

Here's a sample from a video that I've have the stuttering problems above: https://www.dropbox.com/s/i6uz6wqq3yomtza/25fps%201080i%20VC-1%20Test%20Sample%20V01%20%281%29.mkv?dl=0

It's rather hiccuping or clogging than stuttering, mostly noticeable at the beginning with those tall rocks and at the end at the long waterfall shot.
