try to re-encode dv file as RawDV file (open dv, add simple filter like
brightness on top of it, try to encode as rawdv.) notice with patches it
sets date/timecode. And in case of anamorphic 16:9 dv hopefully also flag
indicating so (visible with mediainfo/ffprobe/mplayer)

May be we really need only 0002 but I was not sure if 16*9 flag was  going
down to stream without those new function calls?
