I must have been scanning it incorrectly. I just hooked the fios  
cable back up to the 5500 and tried scanning a few different ways.  
Now I'm getting locks, but I'm not sure what to do next. I scanned  
using scan type "full scan", frequency table "cable high", atsc  
modulation "qam 64" (also tried "qam 128" and "qam 256").

After the scan is done, on channels 78-86, I see "no signal". On  
channels 87-123 I get "no tables". It seems to have found something  
on channel 123, but isn't sure what to call it; default was  
"UNKNOWN123#6". On channels 124-159 I get "no tables".

I'm looking around Google and the myth lists but not seeing anything  
about the aforementioned issues.
