I'm pretty sure for TW it's just "Cable". Those are different
frequency tables that are (or have been) standards in different

I think those are music channels, if TW down by you uses the same
digital cable table as up here in WI. Expect to see a lot of that.
They're all there, but those are encrypted. The HDHR sees the
bitstream but can't do a thing with it.

> Third question. Should I try scanning with something other than QAM-256?

Mmm, no. TW definitely uses QAM-256.

I had the best luck finding the channels I should care about using the
Windows HDHR tools. When you tune a channel, it tells you which
subchannels are encrypted / open, etc. It's fast, and a nice clickable
interface. Using that tool, I found that there are quite a few digital
cable stations that are in the clear (for me) that I hadn't found when
I programmed my locals directly into my TV. These include ABC Family,
Style, Hallmark, etc. You know, the lame ones. :-)

Uh, good luck ? ;-)
