Okay; I'm all for making the web-guide match the gui-guide, but I have
about 300 channels to get guide data for.  If we scan in 5 minute chunks,
using the model in my patch, that's still only 36 queries for a 3hr window
versus ~300 * 2.  I'll have to run some numbers, but I think my method is
still going to be significantly faster.

Can we modify the guidegrid to be more efficient as well, then?

Currently, when I'm in the alternate EPG and move the selection cursor,
my video/audio skips (presumably because Myth is querying the database
to retrieve the DisplayChanNum setting).

I could submit a patch for this "feature", but would you commit it?
