I just boght my first HDTV set and thought that finaly i would be able to watch my dvdr and Mkv in really high res.
But I'm havin issues with dvdr and xvid movies.
Mkv:s encoded in 720p are running just fine, as i know that my CPU is not fast enough for 1080P encoded material.
The DVDr:s are running fine with MPV codec but it makes a jump every 3-5 seconds. Like it's trying to catch up with itself.
And the few xvids i have the picture is lagging behind the sound, it fixes itself if i jump 15secs in any direction. But goes out of sync again.
None of these problems occur outside of mediaportal, if i run the dvdr in WinDVD there are no stutters at all. And mediaplayer runs the xvids just fine. And trying different codecs doesn't help in mediaportal, actually the MPV is the only one that is working. The others are just stuttering all over the place.

If I lower the desktop res to 1280x720@60Hz then all is well, absolutely no problems at all!!. But i bought the set for the high resolution, and excellent blacks.

This has to be an issue with media portal, is it due to the so called pull/down??
I tried different codecs and SVN:s updated all the drivers. But so far nothing has been working proberly.
I'm very content with the .MKV files as they are running just fine, but i wish the rest would fall into place then all would be well.

Any thoughts and ideas would be helpful.

/Best regards
