The scheduler is already part-way (fully even?) to being able to do this
- As you know MythTV already has the card and input distinction in its
database structure. As part of this it is possible to flag a source as
"shareable", marked by the column in the cardinput table. This flag
tells the scheduler that all channels on this input can be recorded
simultaneously.
Whan the scheduler was revamped last year I gave this feature some
rudimentary testing, and it should just be necessary to modify the
DVB/HDTV code to report each MUX as an INPUT on the digital CARD
(requiring a separate SOURCE for each), and set this shareable flag to
"Y" for that input.
If ATSC/NTSC channels are also kept on separate "Virtual inputs" I
believe you have a scheduler that meets requirements :)
Hope that helps.
Steve
