[mythtv-users] Slave Backend Configuration obscure

I have my Master Backend & Frontend working quite nicely with .18.1 and
wanted to add another machine.  This second machine works fine as
a remote frontend.

But I wanted to slap another tuner in this remote machine and use it
also as a slave backend (I'd put both cards in the Master If I had
the slots).

Problem is, with that backend running, there seems to be a problem
with ring buffers:

2005-12-08 00:00:07.405 RemoteFile::Read() failed in
RingBuffer::safe_read().
2005-12-08 00:00:07.621 RemoteFile::Read() failed in
RingBuffer::safe_read().
2005-12-08 00:00:07.837 RemoteFile::Read() failed in
RingBuffer::safe_read().
2005-12-08 00:00:08.053 RemoteFile::Read() failed in
RingBuffer::safe_read().
Couldn't read file: rbuf://192.168.192.7:6543
2005-12-08 00:00:08.084 LiveTV not successfully started

Just shutting down the slave backend cures the problem.

Is there anywhere written a more complete description of which configuration
items are done in which machine's setup?  The main Myth docs seem to
breeze over this bit.

Where do ringbuffers reside when there are two backends? locally
on each machine, or on the master only?

How do you keep ring buffers from getting in collision if they are
all on the Master?




Also, why does the mythfrontend log always say:
"Realtime priority would require SUID as root."
even when mythfrontend IS suid root?
