 I would stop now while your ahead.

Robert is one of the most active developers of mythtv, and probably the only
of the major contributers who still monitors the user forums daily.  While
we all know that improvments could be made to nearly every aspect of mythtv,
arguing with one of the few who actually works to see that it happens only
slows him down and frustrates him.

While we all wish mythtv could be as easy to configure as your TV, it
probably will never be.  For several reasons. For example, in your case,
even if you could scan for channels as easy as you can on your TV... how
then do you relate those channels with the guide data, channel icons, etc.
And what about channels that are not really channels at all... for example,
when I scan QAM I get a bunch of music channels, on demand movie channels
(that may or may not be broadcasting at that moment), and even data
channels.  Of course, mythtv devs could chose to dumb the process down, but
that too would come at a cost (such as no use of those "hidden" channels).

Please, even though your frustrated, keep your comments positive and
inquisitive.  Robert and most of the others who participate on these forums
respond well to good attitudes and folks who are willing to learn.  Mythtv
is not a piece of software... its a hobby... if you treat it as a fun way to
waste time and money, you will not be disappointed.  If you just want
software and a place to complain if it doesnt meet your expectations, check
out snapstream.com or one of the other commercial products.
