I think it's probably more of an understanding error than a
system/RPM/distro error.

I'll do my best to break down what I do to get my el-cheapo BTTV's
from wrapper to capturing content for mythtv playback:

Step one, open package ;)  Just kidding

Ok, So I usually start with TV-Time to see that things actually work,
narrowing my brain burning to myth setup.  So, make sure in TV-Time
you can tune all the channels you *think* you should be able to
(whatever your TV channels are), and that there is audio, and you can
change channels up and down.  If you can't do that, skip to the bottom
of this reply and see "troubleshooting"  If it does, then continue on
next.

So I can switch channels, see video and hear audio, great.  Now to
convince MythTV I can do the same thing.  First thing, make sure no
backend is running on that box:
killall mythbackend
Then, fire up mythtv-setup, and I, for lack of confidence in my
method, go through every section there just to make sure things are
how I want them.  So, in General, go through the screens and check
each setting is correct.  I believe you said you are using a rooftop
antenna, so us-bcast should be your selection for your frequency (use
the arrow button to cycle, don't type in settings unless you have to
for any choices).  Then move onto capture card.  Make sure you are
inputing the correct card there.  Should just be a V4L card, probably
/dev/video0, /dev/dsp, and whatever for vbi, probably vbi0.  Default
Input should be Television.

Move onto the next section and setup a Program Lineup (usually through
Zap2It for us North Americans).  Associate the program lineup
(whatever you named it) with the card you have setup (this pair up is
VERY important).
