And MythTV will do exactly this for digital channels on the same 
multiplex (including the same channel) on a digital capture card with 
multirec enabled.  MythTV will only do the same for analog recorders if 
someone who actually a) uses one, b) cares enough about the capability, 
c) frequently has such overlaps, d) doesn't have enough analog capture 
devices writes the support.

The cheapest, easiest, and most robust solution, however, is to just get 
more capture devices.

Though this problem is also solved by having sufficient capture 
devices...  :)

And it sounds like you're going that way, anyway.  But the suggestion 
applies to everyone.
