I have a Sony KDF 50WE655 and I just plug the cable into the back of the TV
scan and get all the HD stations that aren't encrypted, this includes all
the locals +ESPN.

This won't work. Over the Air ATSC uses the 8-VSB modulation method.
This is the only thing your OTA HDTV tuner knows how to demodulate.
Digital Cable, both standard and high-definition, however, uses QAM-256
(quadrature amplitude) modulation.
There are dozens of other important differences, but this is the most
critical.

I just called them recently about this. If you have standard analog
expanded service, then it costs $10 more a month to get HDTV ($5/month
for the set-top box/tuner, and $5 a month for basic HDTV service, and
you don't get any of the HDTV programming that is only available with
their standard-definition cable service.
If, however, you have a standard-definition digital cable plan, then if
you want HDTV, you only have to pay $5 more a month from Comcast, for
the tuner rental. You also get more programming, because you get the HD
versions of a few of the channels which are available only via the
standard-definition digital cable package.
It's complicated.

Yeah, that's because your KDF-50WE655 can demodulate and decode
QAM-modulated FTA (free to "air", i.e. unencrypted) channels by default.
Expect to see more of this in the very near future.

I thought it was on their web site. $5/month for the HD service (you get a
new box) or for $9.95 you can get the dual-tuner PVR and the HD service is
"free".

I could get the local HD channels by plugging the cable directly into my
Sharp LC-32GD4U LCD.

I think the SIR-T351 demodulates both 8-VSB and QAM.
My similar SIR-T451 gets the local HD channels (except FOX and UPN)
from Comcast.

It must also have an 8-VSB tuner as well because I get (with a little luck
and no real antenna) OTA HD stations in my area. I believe with a proper
antenna I could many of the Hartford and NYC stations giv

Just to clarify, when you say:

You mean "QAM-modulated FTA channels sent over the cable system"
Readers who don't know what's going on might confuse "free to the air"
to mean over the air channels.
