I'm trying to setup a mythtv system (my first, so
I'm a bit of a newbie), but am having problems tuning
channels. I can only tune in two channels cleanly.
I just get grey & white snow on the others.
On the good channels, ivtvctl -I reports:
check SAA7115 input signal
ioctl: VIDEO_STATUS = Sat/Dvd
On the bad channels, ivtvctl -I reports:
check SAA7115 input signal
ioctl: VIDEO_STATUS = Bad
I'd appreciate answers to the following questions, and
any other suggestions people might have. See below for
system info.
Thanks in advance

1. Is it likely that I just have to amplify the signal?
I live in an apartment complex, so there's no telling
how clean the signal is. But does the fact that I
can tune two channels indicate anything? In an attempt
to gather another data point, I hooked a rabbit ear
antenna up to it. I could tune in a couple different
stations. This would tend to indicate to me that it's
the signal that's the problem, rather than the tuner.
Again, I'm in an apartment, so the best I could do is
amplify the signal at the wall jack. Would that do me
any good?
2. There are lots of examples of people setting various
options (especially tuner type) in their modprobe.conf
or modules.conf. My understanding is that recent
drivers autodetect pretty much everything that's
significant. Is that correct? Or should I be tweaking
something there?
3. I thought about trying more recent drivers, but wasn't
sure exactly what to update. Do I understand correctly
that the ivtv drivers just implement the codec, and
that the tuner (saa7115, saa7127 in my case?) are bundled
with the kernel? Since the codec seems to be working,
upgrading ivtv wouldn't seem to be the solution.
