MythTV is working well except for one thing... if I don't use it for several days, when I turn the monitor on, the screen is frozen. Neither the Microsoft remote nor the keyboard is responsive. I have to reboot the system. Then everything's great again.
Apparently, when the system freezes, no recordings are made.
I've done all the MythTV updates whenever prompted. I have zero problems unless I go a few days without watching TV. Strange.
