Just to be clear, on my system, I don't get 0 byte files, I get no files
at all. The "recordings" show up in "manage Recordings", and when I to
delete them they are shown as 0 bytes, but in fact they don't exist at
all.

I have switched the tuner priorities back to all "0" so that the system
will go back to defaulting to the 5500 (tuner #1) in recording. I'll
see if that brings back tHe recordings. The HDHR still has MUCH poorer
reception than the 5500 tonight.
For comparison, backend log from successful recording using the 5500:
