[mythtv-users] LiveTV Pausing issue

@Mike: I have two livetv storage groups defined (1 per physical hard
drive).  Strictly for curiosity purposes, why wouldn't the backend toggle
between the two storage groups?  One show would end on one storage group,
while a new one starts on the other storage group?  Wouldn't that address
the I/O issue, or does the backend not consider that necessary?
