[mythtv-users] Mythtv and Diseqc

[Andrew Hutchinson]

Thanks very much for this patch Arne.  Things are working great now!  I was
making another mistake originally, in that I only created one Video Source,
and then used this source for both Diseqc inputs.  But either way, even if
you create two sources, it won't work without your patch.

I don't think the patch that you gave me is for the 0.19 release of MythTV
however because I ended up having to apply the changes manually, and the
code was different in a few places to what was in your patch file.  Find
below an updated patch for the latest stable Myth release.  Hopefully this
will help some other people out in the future.
