Thanks, this looks good to me.

The problem with DV in MOV is that the packet formatting functions in
libavformat/dv.c are never called at all.

(except for a small piece in dvvideo_encode_frame(), which is just a
hack so that dv_frame_profile() works).

This is the architecture issue I pointed out earlier. If you want
fully working DV-in-MOV you will need to do two things:

1) Fill in all of the headers. This will involve moving
dv_format_frame() and associated functions into the avcodec, and
calling them from dvvideo_encode_frame().

2) Fill in the audio samples. This is the hard one. My first instinct
is to add a special callback function from the MOV/AVI avformat
wrappers, to tell the video codec that audio samples are available.
But I'm not very familiar with the guts of muxing, so perhaps there is
an easier way.
