Seems more likely to be this one.

I see.

What could/should I provide?  I guess I should first open a bug on it.

Fair enough, so then maybe Mythtv channel scanning has to be a two step
process:  1. Where are you, 2. Scan for that locale.

Hardware variances shouldn't really require input from the user.

I'd even be happy to learn what the devs and other users are doing to
make this process easier and less manual every time their cableco remaps
channels.  Surely everyone is not laboring through this process like I am.

I almost want to completely ignore this channel scanner and write my own
using external dvb tools and populating the channels database.  I
suspect somebody else has already done this.
