Problem with LAV Video codec VC-1 in 1080 videos

Hi
My english is not good, so i apologize.

I was having problems to play some WMA videos in 1080p. It played strange, with vibrations and unstable. I saw that the format of that videos is VC-1. I didn't change anything in configuration of the codecs, never. And after to proof many things, i decided desactivate the codec in LAV Video, and now the videos are playing excellent. In VLC, it still playing wrong, but in MPC now this is fixed.

I don't need help, but i want to tell this to notify to the crew, and maybe could help to someone with the same trouble.

Greetings
