So I spent all day today trying to hunt down the cause and fix for this issue:
Problem: If you launch Plex HT from inside Windows Media Center, Plex HT will launch fine, THE FIRST TIME. If you close Plex and return to WMC, then try to return to Plex, You will get a black screen. The system isnt frozen, the controls still work, (so I blindly push the left arrow key once, and then 'enter' and that shuts down Plex and returns me to WMC). If you then close WMC, and restart WMC without restarting the computer, you can again enter Plex HT ONE time.
I have tried uninstalling Plex, by removing the application and the AppData in the Roaming folder, and reinstalled Plex, same issue remains.
I have tried it on 3 separate computers (2012 Mac mini running Windows 7 with HD 4000 drivers, Haswell intel Nuc i3 and two i5s) and they all had the same result.
If you go enable the "adjust framerate to video" AND you enable "Use true full screen instead of full screen window", this above problem happens.
The reason I have to enable "use true full screen instead of full screen window" is that without that option being ticked, the video slows down and skips horribly during 24p playback while the audio track plays along just fine. To get 23.976hz playback with HD audio sound, you have to enable the "use true full screen...." option. And if you enable that option, you get the above problem.
One solution is to set the "enable display blacking during playback" option and restarting the computer immediately after enabling it. If you do this, you can leave the "use true fullscreen window" and 'adjust framerate" options enabled, and be able to switch into and out of Plex and WMC without the blank screen problem. HOWEVER, if you enter PlexHT and start to play a video file, then stop it, exit plex and try to re-enter plex from WMC, the same problem reappears where you get the black screen. If you restart the computer, you reset the sequence.
I think there's an issue with plex not actually shutting down when you press the 'close' option but instead minimizing. I dont know how to get around this. I'm hoping someone here can replicate this problem so I know it's not just me.
