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
