[mythtv-users] Detecting / Recovering from HD channel broadcast changes?

I just had the same problem. I'm pretty sure that Comcast in my area
re-mapped what channels everything was on. I was also doing some
experimenting with my firewire setup at the time, so I didn't realize
it was happening. Looking back, I recall some odd sized recordings or
failures and now think it was due to the changes.
I don't know of any good way to get them.
Once you rescan, how do you recover? Does the scan yield useful
channel names or anything? I am having to go through about 200
channels, 180 of which won't really *tune* and usually end up failing,
crashing the fe or the be after 4 or 5 channels. It makes finding the
good ones a pain in the ass.
