You're asking a complex question.

What I'm after is to figure out if ffmpeg has a bug that requires
submitting to the devel list or if I have a syntax error in my
command. My reasons would take this thread off point.

Back to my original question... Given the following streams, what's
the correct syntax to extract the data stream.

ffmpeg -i "VTS_01_0.VOB" 2>&1 | egrep '^ *(Duration:|Stream)'
    Duration: 00:00:33.99, start: 0.300300, bitrate: 80296 kb/s
    Stream #0:0[0x1bf]: Data: dvd_nav_packet
    Stream #0:1[0x1e0]: Video: mpeg2video (Main), yuv420p(tv, smpte170m), 720x480 [SAR 8:9 DAR 4:3], 
max. 8000 kb/s, 29.97 fps, 29.97 tbr, 90k tbn, 59.94 tbc
    Stream #0:2[0xa0]: Audio: pcm_dvd, 48000 Hz, stereo, s16, 1536 kb/s

So what's wrong with this syntax...

    ffmpeg -y -i VTS_01_0.VOB -map 0:0 -c:d copy -f data foo.data

Produces this error...
