[mythtv-users] Cannot schedule recordings

[marcus]

When I try to schedule a recording I get the following errors and Myth 
says that no recordings are scheduled:

2006-09-03 19:24:13.439 Connecting to backend server: 127.0.0.1:6543 
(try 1 of 5)
2006-09-03 19:24:33.449 ReadStringList timeout (quick).
2006-09-03 19:24:33.449 Unexpected response to MYTH_PROTO_VERSION:
error querying master in ProgramList::FromScheduler
2006-09-03 19:24:49.977 Connecting to backend server: 127.0.0.1:6543 
(try 1 of 5)

(This output is repeated several times.)

I can watch Live TV, but Myth does complain about my channel number 60 
at startup and tells me to check/edit it. Where do I do that?
All programs come through channel 60 because I am using a DBV-T 
set-top-box, which is fed to the PVR-150.

Thanks,

Marcus
