I have read through previous threads on this, and it seems not to apply to my problem. Here's the issue:
--I come out of standby by pressing the power button on the PC.
--Rather than seeing the GBPVR main menu (from which I entered standby), I see the XP desktop with this error message: "Sorry, this system does not support the required VMR9 video render." Actually, the system throws up TWO of those error messages, one on top the other.
--So I turn on my main PC (since my GBPVR PC is in the entertainment center with no KB/mouse), fire up VNC, close each of the two error message boxes, click on my "StartGBPVR" utility icon, and GBPVR launches just fine. We proceed to watch recorded shows without a problem.
--This occurs only intermittently - maybe once every five times I come out of standby.
--I also hear a little "pop" sound typically made by those little XP balloon messages from the taskbar, but by the time I fly up to try to read it, it disappears. Tonight I caught a brief glimpse, and (I think) I saw the word "power".
This system records shows without a hitch, play-back is flawless, and episode guide updates are working great. There's no other problem that I'm aware of - everything is working very well - except this.
Here are the relevant log lines:
From the pvrx2.exe-2.log:
2009-12-09 23:24:40.541 ERROR  Shutting down due to error (probably no VMR9 support): System.Runtime.InteropServices.SEHException: External component has thrown an exception.

at GBPVRX2.xb979ad394703258e.xfb409e85bd292293(String xf18a926310372520)
And this was in the pvrx2.exe-native-2.log from when the system woke up to do an episode guide update at 6:00 yesterday AM. The guide updated just fine (I checked and I have a full 14 days, so I know it's updating):
2009-12-09 05:58:55.515 VERBOSE Able to SwitchD. Checking for VMR9 support.

Any suggestions would be appreciated.
