I’ve never experienced 7MC crashes when the EDID goes away (what happens when you turn off the TV/AVR that is connected), but it is not uncommon to see weirdness with any FSE (full screen exclusive) application is open and the display “disappears”.
Make sure you don’t have anything like Windows Live Display Driver, Mesh Remote Desktop Driver, Logmein, etc running that creates a virtual mirror display. Those can commonly crash Media Center.
Let us know your Intel HD Graphics driver version when possible and can go from there.
Figures the first person in two years that is paying me to install this for him, “weirdness” ensues. So even though the HDMI Detective doesn’t use power you think it will do the trick? It will be hard to swallow the money spent if it doesn’t work.
Btw…This is one of my tips from another article I have pending but if this is a HTPC then turn off Error Reporting and error dialogs. That will make Media Center restart w/o any notification. While it is nice to know when something is wrong so you can fix it…I also would never want my wife to know see it. Depending on where the crash happens, the error dialog can also prevent new RPC connections (i.e. Media Center Extenders).
I’ll update w/ the registry keys later today…not on a Windows system right now
I will get the version of the driver this evening. Being as it is trying to be just a STB no extraneous software installed, vanilla Win7 Ultimate with just the updates and Microsoft Security Essentials and mcecontroller for IP control of MC with RTI products.
