Do any of the tuners have "Use DVB card for active EIT scan" set in
mythtv-setup?
I /used/ to have this problem with this card where I had to reboot the
machine every few days. This was with just one dual tuner card and 2
"max recordings" on each tuner. I didn't change any of the other
delay/timeout settings from the defaults.
Since turning the "Use DVB card for active EIT scan" setting off, I
haven't had to reboot the machine for anything other than kernel
updates. And the machine now has two of these cards (i.e. a total of 4
real tuners) each with 5 max recordings.

Jason
