I have seen good results on my 0.22-fixes setup over the past week
using v1.5 of your patch and a HDHomRun, two FireWire cable boxes, and
a HD-PVR.[1] The signal detection materially helps with FireWire
tuning too.

[1] Out of commission for the time being. What are the causes/symptoms
of the "bug that can under certain conditions cause the HD-PVR to
become inoperable"?
