I am about ready to throw my hands up in the air. After screwing mythtv up
when trying to get 2 tv cards working with it, this weekend I did a clean
install of mdk8.2 and mythtv 7.0:

1) As before I get sound but no video, basically I have no idea where to go
with this next. Xawtv works fine. Suggestions?

2) Due to the fact that using canada-cable results in channels being skewed
by 1 (if I set a recording for channel 45, it actually records the contents
of 44), I have to use us-cable, however this requires (under xawtv) that I
add a tuning factor of -7 for all the channels, how do I do this under
mythtv? Is this even currently possible.

I had this type of off by one tuning until I used the correct module
parameters to set my tuner type. When I did so my picture quality
improved greatly. See the bttv documentation. Before I set the currect
tuner type I had to use canada-cable but now that I specify the correct
tuner type I can use us-cable.
If that does not fix it you might want to look at the finetune field in
the channel table, I think that does what you are looking for.

This has nothing to do with the tuner type as it is set properly. It seems
to be a problem up here in canada, I get this with ALL tuner cards I have
(I've got 4 spread out between machines and they all use phillips ntsc tuners
and all are set with tuner=2 in the bttv options)

I'd rather use canada cable, but it's never worked properly... It certainly
looks better than un(fine)tuned us-cable.b

Heh, I mentioned using that in my original post :-)

Maybe this will help? That way, fine tune in XAWTV, then read into
mythtv?

Isaac already moved my patch to CVS, just use mythfilldatabase
--xawchannels if you need it.
