> Endly I send a file which should be correct

	OK, I have finally had a chance to look at this. Few comments:

	If you have a bunch of video files but none of them have been imdb 
scanned, you get a lot of <NULL>'s in the dialog. 

	I get occassional errors like this:
		
		undefined symbol: _ZN19VideoFilterSettings12setShowlevelEi

	not quite sure where that is coming from. 
		
	I'm not sure this should be a top level dialog. Wouldn't it be better 
to have a "filter" key off of the browse/list screens?
