Completely correct. The process Jay iterates is exactly why certain 
cable channels look like crap much of the time. The equipment he refers 
to is is a real PITA to get "balanced" properly and is also made from 
unobtanium. Every single cable headend system is a balancing act of 
compromises. Murphy simply guarantees that the crappy channel is the 
channel you record from the most.

And for those of you still trying to shove the OTA and cable signals 
into your tuner via a combiner: Please Stop. My house is in the crux of 
the downwind/base/final for a significant regional airport. There's 
enough collateral damage every few months from aborted straight-out and 
crosswind departures already.

Quick answer? Just get a second tuner. I really don't think there is but 
a handful of  people on this list that actually could balance such a 
MATV system given a reasonable amount of test equipment, time and 
refrence signals. If you think you can DIY than have a ball. Just don't 
crap up the guarded airwaves around my home please.
