A good point, especially as those chanids may get reused for different channels
as the providers shuffle things around. Perhaps the database ought to also be
saving, for example, callsign. That's going to be (human) identifiable, and it
potentially allows recordings to be remapped when chanids change.

Mythfilldatabase will fill sources that don't have tuners associated with them.
I currently use them (in the UK) to provide me with 14 days of listings for my
Virgin cable service. (I used to be able to record off this until my PVR250 went
south.) Although I can't use it for recording, it's a useful planning reference.
