There are some other questions that halfway hit this and don't hit this issue - consider the below scenario and confirm if others are having the issue / troubleshooting efforts / and is MS is truly aware.
It's a little frustrating since it's an included (well at cost or free till jan) component, and hinders us from adopting Win8 as our Media Center machine:
1) Windows 8 Pro with Media Center add on - assumption is this machine (in my case ceton) is running your home tv infrastructure - either basic cable / cable card / etc. - again in my case i'm running ceton - using the latest win 8 beta drivers (sure they
are beta - lets not limit it to that being the cause though)
2) Xbox 360 as media center extender - this is my set-top box, obviously using media center extender on this to watch premium tv, recordings, etc
So, Windows 7 worked like a champ with the above scenario. Streaming fine to my Xbox, I was in a land of joy. Upgraded to Windows 8 ... so long as I use MCE local to the Windows 8 box, all is smooth. Once I attempt to watch it via extender from Xbox 360, it goes horribly bad ... issues noted below:
Issues with the setup noted above:
1) The MCE app will occasionally just freeze up and crash, returning me to the Xbox 360 dashboard.
2) Assuming i'm watching a program, if I bring up the guide and try to navigate to find another channel - it will freeze up and eventually lose connection to the Windows 8 machine. I've had limited success stopping playback of live tv, then searching the guide and selecting a program to watch.
3) Frequent network performance warnings - and lag / freezing in TV recordings. Network bandwidth tests indicate all is great (which I already knew since this was working with Win7)
I'll post some of the eventview errors from Win8 when I get home, but i do see some errors reported about MCE abruptly crashing, however searching that data didn't really conclude anything. This issue is able to be duplicated for me on multiple Xbox's - wired and wireless. I think it's a common problem for others, but unable to confirm here locally since my friends said well if you're having these issues, we'll stick on our Windows 7 media center machines for now.
