8.04 Cannot Record Shows in Guide

[Termina]

If I go to Schedule Recordings, and try to record things on the Guide I get this error in /var/log/mythtv/mythbackend.log

I googled some of this, and most people said it was a problem with changing their hostname; I've never changed the hostname (it's always been dvr).

Does anyone know how I can resolve this? Scheduled recordings are not working either.

Looks like I wasn't able to use the 'dvr' hostname to connect to mysql for some reason until I removed a duplicate line in /etc/hosts with a conflicting IP address.

After fixing this, and restarting, I can now record... but the errors remain.

Will this cause any other problems?

Can you post the whole log?
