Attached file is encoded with "Sony DV Software Codec" codec and have 720x576 resolution.
When I convert attached file, the output file will look incorrect:

Output looks wrong with ffmpeg, plays fine with mplayer -vc mcdv (but not qdv)
in 720x576.

ff_dv_frame_profile() returns dv_profiles[0] (525/60 NTSC) for this sample,
correct would be dv_profiles[1] (625/50 PAL), a special case (as for 576i50
25Mbps 4:1:1) is probably necessary.
First 10 bytes of frame (frame[0] frame[1] ... frame[9]):
1f 7 0 0 a0 cb de 0 ff ff
The same problem happens with file created with "Adaptec DVsoft codec":
http://www.free-codecs.com/download/adaptec_dvsoft_codec.htm
The file seems to play correctly as well with dv_profiles[1],
so now what should be done is to find out some similarities with these
2 files (maybe some frame?) and next force dv_profiles[1] to use
with them.
