The problem I have with committing changes is that mine are Sky NZ
specific, and I have no way to test for any of the other services to
see if I have broken anything for them.

It works fine externally to create XMLTV files, so in the past I did
not see any real benefit to making it part of the MythTV code.  But
the ability to get extra data for channel scanning such as the LCNs
is, however, very useful in making MythTV scanning more user friendly.
That could be done using external XMLTV data also, if the XMLTV
specification was updated to add LCN data and anything else that might
be useful.  When I added the LCN data to tv_grab_dvb_plus's output, I
found that there was no way to make it part of the official XMLTV
data, so I had to put it into an XML comment field.  That is useful
for humans when reading the XMLTV file, but not so good for automating
things in a standard way in programs like MythTV.

I think that costs $1000s so I am not likely to want to spend that
much.
