Hi.

I have a problem with XBMC when im trying to watch 1080p .mkv files. I get a lot of framedrops. This does not happen in 720p at all.

Hardware:
2.200Mhz AMD am2 quadcore
Asus M2N-VM HDMI (Nvidia Feforce 7050PV/nForce 630a) "PureVideo HD" compitable
4 gigs of ram

Software:
MS Windows 7
XBMC v.10

My CPU does not top 40% usage when playing 1080p .mkv's

Tried DXVA2 "on" and "off"
Tried both "software" and "shader" rending
Tried Fake full screen "on" and "off"

No effekt - got over 500 framedrops in 180 sec's

If i run the .mkv in VLC there is no problem this is both with and without CUDA

If i rum it in MS Media Center 7 there is no lag ass well.

Please help me as i love the looks and funktionality of XBMC.

Even if i disable DXVA2 the CPU usage doesn't get over 45%

I think this could be a "codec" problem but i am not sure
