After a reboot, anything that accesses the Guide will freeze the pc for about 90 seconds or more. For example, after pc starts up, I try to go to the TV Guide (or just go to live TV), then the pc will appear completely frozen for over a minute, and then suddenly it appears.
It's ok after resuming from sleep, only a problem after a cold boot. It's like Vista is busy doing something with the Guide. If I wait for a few minutes after reboot before trying to show the Guide, it's ok too.
I have tried Free*EPG and OzTivo, rescanning channels etc.. I've applied both guide hotfixes and reghacks, but no difference.
A minor setback to my otherwise stable (...finally...) media centre.
There are some delays between events of type "Service X has started" of several minutes at boot up that might coincide. Maybe if I can pin down the exact time that VMC spaces out and find the surrounding events, None of the other events reveal anything obvious.
I hate EventViewer, so cryptic! I'll keep digging.
I'm also sceptical about Nero v7. How many freakin' processes does it want when I'm not even burning anything... Bloatware!
When the guide comes up in Vista, its talking via a service called ehSched and spins up a process called ehrec.exe. My hunch is that something in the call path is spinning up the ehrecvr service and this is what is causing the big delay.
To test out this theory, can you try the following:
- reboot to get into the bad state and log in.
- from a command prompt, net start ehrecvr
- after the command prompt comes back saying the service successfully started, wait the 90 secs or so
- start MCE
- start live tv.
See if there's the 90 sec delay.
If not, its highly likely that ehrecvr is the cause of the delay.
If still a big delay, then there's some delay as ehrec.exe is starting up.
Background info: ehrecvr is the process that talks to the tuner cards drives and captures content from them. I've seen long delays with certain tuner card/driver/codec configurations as ehrecvr starts up, tries to enumerate the tuners present, and build the capture graphs for them.
Cheers
Mike
