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]):
