[mythtv-users] Problem with changing channel

Sat Oct 25 16:00:22 UTC 2008

I'm having a small problem with my mythtv setup lately. When i click
ch+ from keyboard (or remote) the EIT information for the next channel
shows up ok, but when I hit enter to switch to the channel it always
jumps to channel 1. If I enter the next channel number manually the
change is working.

If anyone have a tips on how I can solve this it would be very much
appreciated. I can see from the log that the backend SetChannel(1)
when failing and SetChannel(305) when OK, but I can't tell why it is
not the same. It should have been SetChannel(305) in both cases.

Extract of backend log when failing:
