[MPlayer-users] libdv, ffdv question

Hi -

	I saw the announcement on the ffmpeg mailing list that 'dv.c' was
	changed to work with NTSC so I rebuilt MPlayer with the latest
	libavcodec and tried to play "pond.dv".

	libdv works but ffdv gives a VO error.   In both cases the audio is
	claimed to be 44100 - shouldn't this be 48000 (which is what I thought
	the DV format used)?

	Below you can see that "mplayer pond.dv" works ok, but "mplayer -vc ffdv	pond.dv" starts (a split second of audio) and exits almost immediately
	with "VO: invalid dimensions!"
