Are you guys running into these problems using the Myth protocol? I
noticed similar issues and they completely go away when I configure the
frontend to use NFS to access recordings instead of the Myth protocol,
even though NFS is also using TCP.

Might be worth trying to use NFS to access your recordings to confirm
that using the Myth protocol is not the, or part of the, problem.

Using NFS to access recordings has one issue when watching live TV,
though: when a show ends you'll end up in the TV menu with the error
"fail too many times to grab a frame" or something like that. This
is due to the fact that the file that was being played does not grow
anymore after a show ends. The Myth protocol handles the transition from
the old file to the new one but the transition is not handled when using
NFS. This means that the test "Then your show ends and a new one begins,
same channel. Choppyness starts again. pause-unpause. your good again."
won't work.
