Although I think something doesn't add up. It wouldn't be elegant... For the dvb-t card to start recording, it would have to think that the program is in one of the channels it can tune to. So I think I should add all the stb channels to the new source (or add the new adapter to the existing stb source), but setting all their frequencies to the only one available - hoping that mythtv doesn't complain - and then trying your solution.

The STB channels would all have the same mplexid and serviceid. MythTV
should have no problems with that - I am pretty sure it does not check
for that.  Then the channel change script would read the channel
number and use that to send the right value to the STB.

Setting up and maintaining the channels would be a manual process
though, as scanning from MythTV would not work.  Probably another
script would be needed to help with that.
