If it  is centered, xawtv doesn't display it in correctly...i've to resize it by hand to see the image.

I agree with you.

No, it doesn't sound like bytes are swapped..
 
In my very _humble_ opinion there's something wrong with the new high-level v4l1 interface (videodev.c) concerning some calls (pheraps the way it (eventually) handles/asks for mmapped memory?): 
I've some problems with other v4l apps too which make me think there's a bug in the v4l1 interface  and i am pretty sure that every method is correctly implemented in my driver...
