Thanks for your response. I didn't see anything unusual before, but I'll take a closer look at the backend log again and report back. I know that my system was not autoexpiring older programs (I keep very few around). Also, immediately reverting back to 7031 fixes the problem.

Sorry, I'm not in front of my setup right, and it's been a long time since I've messed with my channel definitions. Subchannel selections have worked for me from the start (pre-0.17?). If I recall, in the channel setup screen using mythtv-setup, there are two places where you designate info about the individual subchannels on digital broadcasts. There's the name of the channel and the frequency. I name them 9_1, 9_2, etc. and the frequency is 58-1, 58-2, etc. I think I also changed some pull-down menu to specify that the signal is ATSC. And that's it. When watching live TV, I simply type in 9_2 to tune to channel 9, subchannel 2.

For my analog cable channels, I use a PVR-250 card and in the setup, the two (channel and frequency) are the same. The underscore in the channel name is how I distinguish between my digital and analog channels, although now that I think about it, I suppose that's not really necessary since you are always on one tuner or the other.
