[mythtv-users] backend won't record - MYTH_PROTO_VERSION problems

[Andrew Guenther]

Any luck on this problem Mark? I have a fresh install of KnoppMyth
doing almost exactly what you describe.

Mythweb shows:
User Notice at /usr/share/mythtv/mythweb/includes/mythbackend.php, line 159:
Unexpected response to MYTH_PROTO_VERSION 'MYTH_PROTO_VERSION 15':

The backend log shows
'waiting for a thread' a couple thousand times.

Any shows I recorded recently are 0 bytes long.

I'm still diagnosing.
