Mike,
Can you provide any more detail on this tuning difference? I've been having 
the same problem, but randomly, since I upgraded from 0.23 to 0.23.1 about 
three weeks ago. Live TV on all my HDHR tuners seems fine on all the 
configured channels. But unpredictably, scheduled recordings will come up 
missing or 0-byte.

Yes, I can delete and re-add the HDHRs. But, if I can manually fix whatever is 
now wrong in 0.23.1, it'll save a bunch of customizations.

Thanks,
