Hmm. It seems that there is more stuff involved in this problem then.
For test I tried to put 150 % in DPI settings and then MP hangs if I try to play music? And of course the black screen on video is back.
If I have 1080P resolution and DPI to normal it works.
And I use MP in fullscreen also.
Same problem here, some XviD work and some doesn't, stoping the video and restarting it again from where it left worked for 10 times, but now it doesn't work anymore, the only thing that work is changing the zoom to anything other than Normal, it's really anoying, since this remove a part of the subtitle.
I tried several SVN release and thay all do the same, mabye the problem is from the XviD resolution, because the XviD I've done myself (640x???) all work well and those I find on the Internet, usually 608x???
i suddenly had the same problem for some weeks now.
After trying all things already said here I reset my screen resolution from 800x600 back to 720x576. This at first brought no cure. But - don't ask me why - then I recalibrated my screen with the built in adjustment tool (under settings in MP itself). And now it seems to work as it should.
I have had the upper-left "arrow" 2 or 3 pixels right of the edge, probably after a autoscreen calibration of my screen had put the first pixel column outside of the screen. This have not been a problem before, but now putting the "arrows" at the outer most possible edges the video plays fine in "normal" mode.
Solved my problem, I was using the Codec pack called "Combined Community Codec Pack" to allow me to read x264 files, I have uninstalled it and I installed ffdshow alone only and now everything work as it should.
SOmebody know how to read x264 files other that using Combined Community Codec Pack ???
