Well, I think it makes more sense (long run) to convert the internal structure
over to something more similar to the DD format (separate episode / schedule
tables), and convert other XMLTV grabbers to that. Right now, converting DD
-> XMLTV, there's quite a bit of information being lost, but XMLTV -> DD
should work perfectly..
Anyway, in terms of short term development, yes, a small perl script to grab
the data and then parse and translate that internally instead of depending on
tv_grab_na_dd to do it would be fine. I'd lean towards temporary tables, if
only to cut down on the raw memory requirement that converting the format
