Hello All,
just for your Info:

The latest "Windows 8.1" Update Rollup KB2889784 released yesterday on 11/13/2013 will brake video playback and Live-TV in MediaPortal 1.5.0 Final. Problem exists on two Windows 8.1 Professional machines.

When playing any video you can hear sound but you will get a black screen.
Starting Live-TV will result in an Stream-Error message. "e.g. Cold not start STREAMxxx"

It seems, that the update changes anything with the registered codecs.

If your machines are affected too, simply close MediaPortal, reinstall the LAVFilters with "MediaPortal Extensions Manager" and start Mediaportal again.

This fixed my issues.

I did this windows 8.1 update today and it actually made mediaportal 1.5.0 don't start AT ALL. Any solution coming? I'm now trying a system restore "point" to put my windows 8.1 installation to BEFORE this windows update.. I hope it will work. Anyone got any tips on this?

ALSO: Sometimes during video playback on my windows 8.1 system mediaportal goes from fullscreen to smaller window (like 1/3 of the screensize in the top left corner) for no reason and I have to exit and restart mediaportal to make it work...
