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

   I take care of two back end machine. One is here at my place, the
other is remote. At the remote location mythbackend has stopped making
recordings. When I run the frontend in a terminal I see this:

2005-12-01 09:29:28.705 ReadStringList timeout (quick).
2005-12-01 09:29:28.705 Unexpected response to MYTH_PROTO_VERSION:

2005-12-01 09:30:33.328 ReadStringList timeout (quick).

   Browsing around I found a common reason is a mixed frontend/backend
setup. Mine are not. Both the fronend and backend are 0.18.1.

   Mysql is version 4.0.25-r2 which was probably updated fairly
recently on that machine, but my good machine runs the same version.

   The machine is running a newish 2.6.14 kernel, ivtv-0.4.0 and I see
these messages in dmesg:

ivtv0 warning: ENC: REG_DMAXFER 2 wait failed
ivtv0 warning: DEC: REG_ENCSG1LEN wait failed

   I'm lost for concrete ideas at this point. I could rebuild MythTV,
or the whole system I suppose. I could also possibly go back to an
older kernel.

   Looking for ideas.
