I only mentioned that due to #1 above, if that's not a problem then there
is no reason, however, the wiki does not appear to be up to date. It tells
me that I need to delete and re-add my channels, but in the specific
instructions under  "Deleting and re-adding channels" it says to go into
the channel editor (which would be too slow) and in the next sentence says
to select video source and delete.

Then it says to un mythfilldatabase but after I did that it refused to run
saying there were no video sources configured.

I used mythtv-setup to set them up but its very "clunky" the way it works
but per the instructions I thought this the sqlite grabber had to be setup
from the command line but nothing in the instructions seemed to actually
insert the video sources.

I'm a pretty experienced linux user, been running MythTV for 10 years, and
a Fedora packager for 8. If this doesn't make sense to me I can't be the
only one confused by this process.

Also I've been doing this all as root because the backend user mythtv
doesn't have a shell. I'm assuming I'll have to move the resulting .xmltv
and .SD files to /etc/mythtv when complete.

Thanks,
Richard
