Ok, I just checked out

git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-next.git

as of commit 4d0f480e360a58fc089c2a2f1279945d3c0e79e3, built for migor and 
tested tw9910 with mplayer:

mplayer tv:// -tv \
driver=v4l2:width=720:height=576:device=/dev/video1:norm=PAL:outfmt=nv12 \
-zoom -x 320 -y 240 -vo fbdev

- worked as expected. This is some patched mplayer, but you certainly have 
something to test with too.

Yes, sent to the list exactly a week ago - on the 2nd of September.

Well, yes, the patches do not apply again. I do not know your schedule. 
Would it be ok, if we wait until these image-bus patches get reviewed and, 
hopefully, applied, or, maybe I put a patch series again on a server, 
including these three patches, after rebasing them on some downloadable 
tree, so, you could base your patches on that? Cannot promise this would 
happen very soon though. Or you can fix up my patches on the current 
v4l-next yourself - it shouldn't be too difficult.
