[mythtv] Scheduled recording records on both networked mythtv boxes?

[Mark Chou]

Anybody else see the following behavior, or I'm I the only one going insane?

I have a weekly recurring recording Sunday night from (slightly weird) 
2335-0005 ("Ebert & Roeper").  For whatever reason, this show gets recorded 
on *both* my networked mythtv boxes.  This seems to be the only show in which 
this strange behavior occurs.  FWIW the networked mythtv boxes are synced via 
NTP.

Could the day/week transition be throwing off the master backend?
