On Windows 7, I was able to stream ZunePass music to my Media Center Extender on the XBOX with no problems. With Windows 8 and the Media Center add on I just got, every Zune Pass/XBOX Music pass song now fails. I've even placed the music in an M3U file and still nothing. Any fix for this?

Also, on non-drm music playlists, when I am also doing a slideshow with the music, it can take 15-60 seconds for the next track to start...again, this never happened with Windows 7.

Any suggestions? Thanks!
