Right, but the "x" in "x hours," above, is limited to the maximum length 
of any one show on the channel that's being recording (with an 8hr cap, 
IIRC) times the number of capture cards stuck in LiveTV mode.  That 
means that if LiveTV is recording a channel continuously and the longest 
show it records is 3hrs, Myth should only ever need to expire shows to 
make room for the 3hr show and, as soon as each show finishes recording, 
Myth will be able to expire the just-recorded LiveTV show since LiveTV 
always expires before recordings.  (True, there is some extra space 
required because of when the autoexpirer is actually run (every 15 
minutes, IIRC), but worst case, Myth will need enough space for 2 
back-to-back shows.)
