[QUOTE="mm1352000, post: 799144, member: 82144"] Hi again No need to apologise - I understand that you're new and I didn't mean to come across so grumpy. :sorry: This is precisely what makes me think that frame/refresh rate issues are involved. My opinion is that EVR works with the TV content because the 29.97 fps frame rate is a close multiple of the display refresh rate (60 Hz) and it doesn't work with the movies because the 23.976 frame rate is not even close to a multiple of 60 Hz. As a result, what you see on the screen is the choppy playback. In the logs what I see is constant media type changes between 59.94 fps and 47.952 fps (which are double 29.97 and 23.976 - the Microsoft codec and/or renderer don't like this. When I mentioned this issue to Owlsroost and Tourettes who are two of our most experienced developers in this area they said also to check whether the hardware is not keeping up, which is why I asked about your CPU and GPU. Please do try enabling the [URL="http://wiki.team-mediaportal.com/1_MEDIAPORTAL_1/141_Configuration/MediaPortal_Configuration/12_General_1.2.0/4_Dynamic_Refresh_Rate_*"]refresh rate changer[/URL]. It is in MediaPortal configuration in the "Dynamic Refresh Rate" subsection of the "General" section (as per the tree on the left hand side of the wiki) - just tick "enable dynamic refresh rate control" and see how you go from there. What I can't explain is the behaviour of VMR 9. However, I still stand by my recommendation to stick with EVR... mm :) [/QUOTE]
