To be clear, you should have two different video sources defined.
For the channels that carry the same station, the "callsign" should
be the same.

You cannot specify the tuner but presumably you have one source
for DVB associated with the DVB input and a source for the analog
channels associated with the PVR-350's input.

I do this all the time. In fact, I use chanel priorities to switch
which input is preferred sometimes for special cases.

|   2123 |        2 | 123     | KVBC     |           0 |

KVBC is on analog 3 and digital 123. My analog inputs are lower
numbered than my digital so it prefers channel 3 by default.

LPGA Golf - "Samsung World Champion    3 1003  16 10:00-13:59  1 1 1  S 1   3


If I go to TV Settings->Recording Priorities->Set Channel Recording
Priorities, I can lower the priority for 3 to give showings on 123
the advantage. I don't want to give 123 an advantage over all other
channels so I lower 3 to gain this effect.

The priority for "LPGA Golf" is 0, Single record is +3 so the total
priority for a single LPGA Golf on 123 is +3 but only +2 on channel
3 so 123 wins. If there was a higher priority show that needed the
digital input then "LPGA Golf" would record on channel 3 from one of
the analog inputs.
