The number of channels is small but the number of programs is huge compared
to someone running 30 or 40 program schedules (maybe 100-200 showings total)
vs. 3 channels running 24 to 48 programs each, maybe 100 programs over 14
days (1200 or more showings). I think the suggestion to only download 1-2
days of listings is a good one. Turn off the automatic mythfilldatabase
option in your setup and just run mythfilldatabase with the option (run with
--help for info) for max days set to one or whatever the option is to
download just today and tomorrow.

Maybe not, but it's also not likely to hit the radar of many developers
because it is an unusual configuration. I think the limiting of program
data is your best option because it fits best in your setup
