Bob,

If you look at the frequencies of both you will find in most cities cable a=
nd ota overlap here and there.
There use to be a BLOCK shifting converter that shifted VHF channel block u=
p to UHF block.

BUT

For the most part you already have most of the OTA signals integrated into =
your cable signal.

FREE-QAM

There is/was a FCC requirement that ALL local OTA channels be available on =
cable without requiring a cable box.

This means both analog AND digital before conversion and digital after.

They are not required to advertise it but they are required to supply the s=
ignal.

So a standard HDTV should be able to receive standard analog cable channels=
 and Digital local channels without set top box with just basic cable.
They often switch exact frequencies of these channels so you might have to =
scan analog/digital every so often.

The trick is to get a quad cable card tuner for your win7 media computer an=
d ONLY pay $2.50/month for equipment.
TWC will try and sell you bundled packages and tell you are required to als=
o rent set top box and remote to get the bundle discount.
($12/month) You have to keep going up the chain to get to the right person =
to understand that a bundle should include the required items.
Needing (as opposed to requiring) a set top box to use all the features als=
o is a clue.
I never used on-demand or pay-per-view.

Anyhow cable signal ALREADY has both cable and OTA signals.
