Yea, sorry I was thinking someone would just tell me it wasn't supported.

Here's a test that shows the issue -

http://streams.videolan.org/samples/MPEG2/interlaced/burosch1.mpg

Chosen because it's bff, if I make a stream.yuv with mplayer using -vo 
yuv4mpeg (:interlaced or :interlaced_bf make no difference) I can't get 
it to deinterlace properly whatever field-dominance I use.

If I replace stream.yuv with burosch1.mpg it works of course - and I can 
break it with -field-dominance 0.

It's not just yuv4mpeg/i420. I first noticed on a v4l capture which was 
avi containing yv12 - Selected video codec: [rawyv12] vfm: raw (RAW YV12)

bash-3.2$ ./mplayer -v -vo gl -vf yadif=1 -field-dominance 1 ~/stream.yuv
