[mythtv-users] Analog tuner - can't change channels

I've just reinstalled my mythtv box, and I'm having trouble getting channel changing to work.
This is a combined frontend/backend, running on Ubuntu 10.04, with the mythbuntu packages, on version 0.24-fixes.20120112
In LiveTV, myth will tune to the starting channel, but changing channels either gives me an "Unknown recorder error" or locks up the frontend until I manually kill it. Scheduled recordings also fail, with an message about being unable to change channel
I've tried two different tuners - a generic PCI card (claiming to be a Sabrent SBT-TVFM) and a Hauppauge 61381, connected to analog cable.
They work properly with both tvtime and xawtv, and under previous myth versions. I can also start LiveTV and change channels manually with v4l2-ctl
So, the problem seems to be somewhere within myth, but I'm not sure what to check at this point.
I've also compared my channels table to a backup of my previous one, and they appear to be similar
I also found that scanning for channels using the hauppage card crashed mythtv-setup every time, while it successfully worked with the generic one.
Here are some logs (with -v channel), watching LiveTV with a starting channel of 3, trying to change it to 4, using the generic PCI tuner card.
