My stability problems with the newest build of MC are not gone, unfortunately. However, I believe that the problems are with G-Force (v2.8) rather than directly with MC ... I suspect that these problems are due to some change in MC though, because I believe I've been running G-Force 2.8 with MC11 for some time without major problem until the more recent (.210-ish) builds. Plus, the problem seems to be getting worse with each sucessive build of MC.
The Media Core error signature:
AppName: media center.exe AppVer: 11.0.220.0 ModName: g-force_api.dll
ModVer: 0.0.0.0 Offset: 000699e9
If I revert back to .218 the problem isn't as bad, but is certainly still an issue. I may roll back progressively to see if I can find the start of the problem, and can post debug information if needed.
On another different (but similar) machine, I have MC 11.0.201 and G-Force 2.71 installed and they work fine. I will also upgrade this machine to .220 and see if there are problems with the older version of G-Force (or if it is specific to 2.8).
If anyone else is suffering from signifigant stability problems when using MC11.0.210+ builds and G-Force 2.8, it could be that you have an outdated copy of G-Force. It appears that G-Force was changed after it was initially released due to problems with crashing and iTunes in Windows, but they didn't increment the version number (I hate that)....
http://soundspectrum.com/v-web/bulletin/bb/viewtopic.php?t=359I was having a lot of problems with G-Force, using a build modified 2005-02-18. If your copy of G-Force is old and you are having problems, you may want to re-download it. I found no mention of problems with MC related to this older build on the G-Force forums, but I tried it anyway...
My problems went away completely.
