Yes.  When you're modifying code in a large existing project, care should be 
taken to make your new code feel the same as the existing code.  Cursors 
aren't used anywhere else.

Also, using a non-random indentation style would have been appreciated.  
Please look at the rest of what I changed as well (aside from moving stuff 
around in videosource.cpp/.h).

It seems to me that the current parser is _very_ fragile 
(DDStructureParser::characters(), for instance, looks rather easily broken to 
me).  There's a reason that Qt's DOM parser is used everywhere else in myth 
-- I'd like to have this eventually switched over to that, but what's there 
works for now.

I'd prefer not to have it enabled.  For every 1,000 people using the grabber 
(and using your quoted numbers of 2MB vs 300kb per day), that's, what, an 
extra 50GB of completely unnecessary traffic for zap2it's servers per month?
