Hi and sorry for my english.
Problem:
With windows XP SP3 my HTPC(ION) work fine, all MKV and BD play without any problem(in MP). If i try play some file in windows 7 media player, all work fine too (no lags). But if i play it in MP (all MKV 720 1080) it stop normal play (very low FPS) but ffdDXVA codec is active (icon is show). In config, for H264 - ffdshow DXVA. I dont know, why in the same time (on win 7), WMP and MP play same file with same codec, but with different quality.
