It seems to only be an issue with YUV 4:1:1 480i DV streams, I'm not able to 
reproduce the issue with YUV 4:2:0 576i DV streams.

Unfortunately I don't have access to any NTSC DV sources, but might get a 
chance to borrow something later in the week (and see if I can debug the 
issue using Microsoft DirectShow's GraphEdit).


Cheers,
Doug
