You might have something there because I think this last time, I let it sit while away for dinner before I started it up to watch TV and see what would happen. I'll put the other card back into the mix, restart the server, wait a while and see what happens.

Yes, both are still listed, but with the error

/dev/dvb/adapter0/frontend0
ERROR_OPEN Subtype: DVB-S!

and 

/dev/dvb/adapter1/frontend0
ERROR_OPEN Subtype: ATSC

Only what I posted of the log snip. Unless there's another log I should be looking at, I didn't notice anything off hand.
