Thanks Ed, for trying to mediate.

Looks great to me.
Just add AC3 maybe, if that's important to distinguish from audio (it's
a totally different data format). But Kenneth probably knows better, as
it's the CAM support which is the current, main reason for separating
the columns at all. Just a data point: I think it's entirely reasonable
to have both a stereo (incl. Dolby Pro Logic) and an AC3 (=Dolby
Digital) stream, and the AC3 stream isn't always present/meaningful,
while the stereo stream is always present, but the AC3 stream is
preferred, if it's meaningful (not sure, if that can be determined by
software). So, personally, I'd include an "pids_ac3" field, but I don't
know all the technical details (incl. CAM) to form an educated opinion.

Yes. Thanks for pointing out that we might end up with e.g.
"456,457,,,,". I checked the Qt docs and the split function by default
does not return empty entries, so we don't have a problem here, you can
remove the comment.

Personally, I'd leave them out for now and include them in the
mythchannels patch, but I leave that to Isaac. (But I agree with what he
said so far.)
