Ignore this message, FCP complains because audio chunks are not
containing ~= 48000 samples which is completely non efficient.

I usually force the audio to avoid issue with odd sample rates, and add
an aspect tag:-
-i infile.fmt -vcodec dvvideo -s 720x576 -aspect 4:3 -pix_fmt yuv420p -r
25 -acodec pcm_s16le -ac 2 -ar 48000 out.mov
I have not had a problem with the 4cc.
