I think you misunderstood my point. You and Daniel seem to be
suggesting is may be an NFS problem, but I was pointing out that this
problem happens when always stream is on, which means NFS shouldn't
have been a factor with that enabled (as far as I'm aware)

Yeah, but my point was to find the cause of the problem. If theres a
bug there, I'd like to report it. If it makes you happier, then rather
than just force "always stream", I can just unmount the nfs volume to
force it to stream and test it that way. Better :-)

The thread was this one:
www.gossamer-threads.com/lists/mythtv/users/501485

And I believe the magic line that did it was:
socket options = TCP_NODELAY SO_RCVBUF=262140 SO_SNDBUF=262140

My old config had 4096 as the buffer size.
