[mythtv-users] Migrating the backend

[shacky]

Hi.

I tried to migrate my MythTV backend from the old server to a new one,
and the backend starts without any problem.
The SQL connection to the "mythconverg" database works without any
problem from all my LAN network with the "mythtv" user, and it works
from the frontend too.
The problem I have is that when I try to watch TV from the frontend
installed on the same machine of the backend or from a frontend
installed on another machine in the LAN I get this error in the
backend logs:

2007-10-27 00:46:00.616 DB Error (insert_program -- lock):
Query was:
LOCK TABLES recorded WRITE
Driver error was [2/1044]:

Database error was:

What's the problem?
Anyone could help me, please?

Thank you very much for your help!!
Bye.
