 VLC and totem play this file fine. FFMPEG says it can't detect the format.
 A file produced exactly the same way has the following format:

 Input #0, dv, from 'capture004.dv':
   Metadata:
     timecode        : 00:00:02:16
   Duration: 01:00:44.16, start: 0.000000, bitrate: 28800 kb/s
     Stream #0:0: Video: dvvideo, yuv420p, 720x576 [SAR 16:15 DAR 4:3],
                  28800 kb/s, 25 tbr, 25 tbn, 25 tbc
     Stream #0:1: Audio: pcm_s16le, 32000 Hz, 2 channels, s16, 1024 kb/s
     Stream #0:2: Audio: pcm_s16le, 32000 Hz, 2 channels, s16, 1024 kb/s



 I cannot attach the file in question because it is several gig big. If
 there's any way I can do this without sending whole file (e.g. send first
 20Mb or something) let me know.
