 Minor Problem: Channel scan finds 100s of invalid, non-existent channels.
 Tuning to an invalid channel in LiveTV crashes to main menu.

 Major problem: No fast way to recover. Fastest way is to close down, run
 backend setup and manually change the starting channel. No big deal if
 it's one channel, one time. 5 minutes or so to fix. Major problem is that
 if you are trying to label 500 channels, 200 crashes are going to add an
 extra 16 hours to the time it takes.

 I regret to report that this has been a problem since at least version
 0.18 (see link). I have seen lots of people asking for this to be fixed.

 Forget about fixing the "crash when the data is bad" problem.

 The real problem (can't quickly recover from crash) is an incredibly
 simple problem to make a good workaround. Please accept my suggestion for
 one or more of the following seven ways to workaround it.

 1) On crash, return to last working channel
 2) On crash, return to a pre-set channel (e.g., channel 2_1)
 3) On crash, tune to analog tuner (for those of us with analog and digital
 tuners)
 4) Option for a "what channel do you want" to pop up when selecting live
 TV, before trying to turn to TCC (the Crash Channel).
 5) An option to have a fixed starting channel rather than a variable one.
 6) A simple command line program to change to another startup channel
 while frontend is running.
 7) Let us tune to a channel from the channel guide in "schedule
 recordings" instead of only live TV (which crashes before we can get
 there).
 8) When it crashes, offer the option to delete the channel then and there
 (then tune to default channel when starting).

 In short, if you can't stop the thing from crashing on particular
 channels, please provide some very fast way to get away from a bad
 channel. I would be happy to tab to a terminal, then re-run a command line
 every time it crashes.

 If it matters, I have HDhomerun. Oh, and this isn't the SD/HD bug. It
 happens regardless of what channel you start from, only the destination
 channel matters.

 So could somebody please, please fix this so that those of us whose cable
 company shuffles the channels from time to time don't have to spend days
 weeding out the bad ones?
