what unencrypted HDTV channels via QAM? I think you are more likely to find
unencrypted SDTV channels on QAM, if they are available there in that form.
Methinks that most to all DTV channels are only available in encrypted form, at
least on the major systems.

My comment was primarily directed to using the QAM tuner for unencrypted HD
channels.
However, many more unencrypted SD programs are becoming available for the QAM
tuner.
From the ones that I have seen, they are a significant improvement over their
former analog versions.
Most of the cable providers are in the process of "upgrading" to a DIGITAL
SIMULCAST capability, wherein ALL of the analog channels are being replicated
as unencrypted multiplexed SD channels. Eventually, most if not all, of the
analog channels will be replaced by more HD channels (et. al) in order to match
D* and E* upgrades.
TWC-Raleigh reports that their conversion was completed about a month ago. On
our local TWC-San Diego, the transition to Digital Simulcast is about 4/6
complete.
They are packing 13 analog channels into each of six unencrypted QAM-256
multiplexes.
Since many of the formerly non-local analog programs are now being transmitted
from source-to-destination as all digital MPEG2 signals, we have noticed a
significant improvement not only in the digital SD programs but also in the
analog programs that are apparently being reconstituted via a local D/A
conversion. Sci-Fi channel is a lot less blurry (but sadly, not HD).
The accumulative degradation of the analog signal has been eliminated, which
was no doubt being accerbated by using the oldest, worst-of-the-worst analog
channels on C-Band.
Advanced StatMuxes at the program generation center are claimed to help
minimize artifacts...but let's face facts, these are highly compressed SD
programs and are nowhere near as good as SD programs on Premium channels.
I'm still comparing 1) OTA-NTSC and 2) Cable-NTSC to 3) Cable DVR-NTSC and 4)
Cable DVR-QAM. Thus far it looks like a tie between 1) OTA-NTSC and 4) CATV
DVR-QAM (Digital Simulcast). The 2) Cable-NTSC (direct connect cable to HDTV)
is slightly grainy. The 3) cable DVR-NTSC signal is obviously degraded, since
it goes through an extra analog to MPEG2 to HDMI conversion process in the DVR.
I do not have a Cable QAM tuner, so cannot comment on that option, but I have
seen reports that it is equal to better than any of the above, since the HDTV
is presented directly with the MPEG2 digital signal.

No attempt to bring you quality, just quantity.
On a 19 inch TV who can tell?
