I take it this is a command I should run. Where should I be running it? 
Also, I'm guessing this just flushes the old programming data. Will 
MythTV automatically rescan for programming data when it sees that the 
guide is empty, or how do I force a programming guide scan?

That's what I thought initially too. However, when I look at the episode 
information with a digital converter box (same broadcasters, but no 
computer/MythTV involved) all the episode information appears to be 
accurate. Same day/hour/channel/program on MythTV: episode information 
from another program on the same channel. It's also happening with *all* 
the channels. I can imagine that some of them are incompetent, but at 
least one of them should get things right, shouldn't they?
