channel tuning fails without serviceid/mplexid

Description

I'm not sure how it happened but one of my channels lost its serviceid and mplexid values (they got set to null). I tune the source with either Firewire or cablecard (hauppauge dcr-2650 / hdhr prime) -- both types of tuner exhibited the problem.

These values are not used for cablecard tuners, but with them set to null, recording and live tv would die and kick me back to the main menu. Backend logs show:

I'm not sure why MythTV even needs to be trying to tune a virtual channel when interacting with an input type that doesn't use them (firewire and cablecard).

I figure this bug is probably of low importance, except that mythtfilldatabase --do-channel-updates didn't fix the values like it presumably should have. Together, these two issues made for a lot of missed recordings.

Just because it was pointed out that the error was for the HDHR only, here's one for firewire:
