1st of all thanks for the reply and info... I tried changing the video rendering mode and there are many outcomes the best i think is VMR9 renderless and VMR7 with the "use YUV mixing mode" ticked but still having problems.
When using VMR9 renderless, there is 1 window but the dvd menus are unclickable.
When using VMR7 the menus are clickable but an error msg comes out saying: "failed to allocate subtitle surface. Subtitles will not be available." Don't really care but when playing there are 2 subtitles over each other.
VMR7:

Please help and thanks again.
