[FFmpeg-user] This strea is something else ?

[Bazza]

I'm seeing this quite a bit. Especially if I use a -target command.

Of itself, I don't mind that there's a 'dvd_nav_packet' stream but
 it does seem to intefere with other subsequent conversions. 
The example output text below  is  from a vob file generated by
 the Sony Vegas editor. FFMPEG will also generate the *0x1bf' as
I mention above but does it really need to 'classify' the nav_packet
as being stream #0 ? If it does, where can I find the reasoning 
behind this? (Using Zaranoe Windows version)
