And maybe the straight-forward scheduler could be made fast enough so it 
can re-assign a recording to a different card when you're using the 
scheduled one for Live TV.

Last time I lost the end of a program because I was half an hour behind 
on Live TV and suddenly it comes up telling me it wants to use the card 
for a recording while the other card was doing nothing! As a certainly 
didn't want to lose the scheduled recording I had to decide to ditch the 
program I had been watching. I can tell you my significant other was 
_not_ amused!

(But maybe this could be handled by the current scheduler by adding a 
new option "try to reschedule the program" to the pop-up asking you what 
to do with Live TV?)
