I have media portal working perfectly on my normal pc (i set it up to test. now im building the real thing)

Im having problem with the internal player. It will play the first movie fine. but when i stop it. it leaves half the movie on the screen (see first screen shot). so then i click Stop. and it gets rid of it. But when i play the next movie file it will crash mediaplayer.exe (second screen shot)

I have tried a couple of different codecs. most of the ones in the plugin section. as well as K-Lite. I have uninstalled them and reinstalled them seperatly and tried it. still same deal.
the movies will play fine in media player. just the internal one.. I have also played around with all the options trying all the options in the movie player.

I have tried dscaler. and everything nothign seems to work.

any ideas?

also it works fine if i dont use fullscreen..
