[mythtv-users] Dual tuner info

That makes perfect sense, but what I'm confused about is what I experienced before.  When I had the digital cable source assigned to only one tuner, I had trouble changing to a digital channel:

1. I was watching basic cable on Tuner 1 (that had only basic cable attached)
2. I attempted to change to a digital channel.
3. Tuner 1, not having the digital cable as a source,
4. MythTV wouldn't switch to Tuner 2 to complete the channel change

Is this unrealistic at this point?  I recall your recent post about MythTV not being able to automatically switch tuners, but it's higher on my WAF than risking digital cable on both tuners...

With one cable box, no, only one card should have the digital channels assigned, because your cable box can only output one channel at a time.

If the input is in use, Myth knows it is in use, and won't try to change to it.

Judging from your last sentence, I think you may have some confusion as to how the cabling would work... You should have a splitter that breaks the signal up into 3 distinct coax connections. One goes to the cable box, one to the tuner input of each of your cards. The cable box then feeds the SVid or composite input on one of the cards. The only time anything flows through the cable box is when you're recording or watching a digital-only channel. The two tuner inputs don't give a rip about the cable box.
