That definitly has something to do with the capture sizing or refresh 
rate or such. It can also be that it misses out on the interlace and 
expects all lines in order. Pal in Europe is most times 50 Hz, 625 line 
(576 visible) interlaced picture. Where NTSC in the US is 60 Hz, 525 
line (480 visible) interlaced.
