[mythtv] [PATCH] DataDirect service -- updated to match CVS xmltv tv_grab_na_dd

[Robert Kulagowski]

If you're feeling froggy, mythtv used to support grabbing data directly 
from a site called "gist.com" and didn't use XMLTV at all.  The diff is 
here: 
http://cvs.mythtv.org/cgi-bin/viewcvs.cgi/mythtv-backup-preshlib-old/programs/mythfilldatabase/filldata.cpp?r1=1.44&r2=1.45

Back then, Isaac just called wget to pull the data.  Might be a way to 
directly support Data Direct without trying to shoehorn stuff into the 
XMLTV 0.5 DTD that doesn't quite "fit" right now.
