That stand-by tuner issue you have sounds serious though. The use of stand-by in a MCE PC can be very important, so too can the use of all available tuners upon resume.
Have you been experiencing missed scheduled recordings due to this issue?
How do you recover from this, close/restart MCE or reboot the system?
Did you open a trouble ticked?
It looks like you and “denyart” have the same problem. Hopefully Bill T will be back soon to help you two out on this.
Hopefully, something as simple as a driver update will fix this.
Yes, stand by is very important for me.
I haven't experienced missed/scheduled recordings because all my recordings are scheduled in the evening when the PC is on anyway - but the fact is that if it came out of stand by, only one tuner is useable no matter what.
I recover from this by rebooting, simply closing MCE does not fix it.
I opened a ticket, but so far they only asked me to submit system information and a problem file generated by their utility.
