Wow.  How in the world did you configure your system to record something 
that's airing several days from now?  With this functionality, we Myth 
users could actually watch and rate an episode of Heroes before anyone 
else in the world can see it.  ;)

In other words, it doesn't affect recordings because by the time they 
air, the listings are current.

Yes.  This /only to be used as a one-time fix/ setting can be used to 
verify that things are correct.  Note, however, that you should *not* 
put the "--refresh-all" argument into your mythfilldatabase arguments 
setting for MythTV (i.e. don't do it normally).  It's significantly more 
work for the listings provider.

The reason that it wasn't a problem--even before you refreshed your 
program listings--was because Myth always downloads tomorrow's data (in 
addition to the new data at the end of your listings--i.e. +13 days).  
So, when you download tomorrow's data, it fixes the broken data for that 
day.  That means that had you left things as they were, each "broken" 
day would have been fixed before the day began.  Note, also, that the 
days in the middle of the guide are left as is--a "so you have a pretty 
good idea of what's on" guide--because they're irrelevant to the actual 
recording process until they're current, and they're always "fixed" 
before they become current.
