"Error opening jump program file" when switching Live TV channels

[Trevan]

Binary package hint: mythtv

I'm running MythTV .24 and Mythbuntu 10.10. When I select Live TV, I can watch the current channel fine. But when I attempt to switch channel (press UP multiple times, press SELECT), it blacks out and then exits to the main screen with the message "Error opening jump program file". In MythTV .23 and Mythbuntu 10.04, there was no problems with switching channels.

The mythfrontend.log output is:
