Hmm... odd.  The master thinks the slave is recording, but the slave 
thinks it's free.  Was the status from the master & slave taken at the 
same time (i.e., which one did you query first and did a recording 
start or finish in between getting the 2 status reports?)

Makes sense, since the master backend (which runs the scheduling code) 
thinks the slave's tuner is busy.  Since that's the only tuner that can 
get a DVB channel, it won't let you watch LiveTV on a DVB channel.

Right; since the master thinks the DVB tuner is busy, if you're watching 
LiveTV it must be using one of the tuners in your master backend, which 
can't tune DVB channels.  You *could* use the 'Y' key to switch cards 
in LiveTV, but in your case that wouldn't work since the scheduler 
still thinks the DVB tuner is busy.

Looks good...

Why is this wrong?
Encoder 1 -> DVB card on pvr2 ('remote' as seen from pvr [master])
Encoders 2 & 3 -> PVR-x50 cards on pvr ('local' as seen from pvr 
[master])

You should be able to watch this from any frontend (provided it's 
powerful enough to decode the DVB-encoded MPEG-2)

Not sure if I followed that...

Right; again, you're watching LiveTV from one of your PVR-x50 cards; to 
switch to a DVB channel use 'Y' to switch cards first.
