[FFmpeg-user] capturing .dnx together with -segment

Trying to capture to raw  DNxHD (*.dnx) while using the -segment option.
That fails.
Close to the same line (capturing to a QuickTime container) does work.

Am i missing something?
Lines (simplified, but enough to reproduce) below, first one is the failing 
one.

Second is the working one (although that 'should' not need the -rawvideo 
option)
But this gives me errors (that don't seem to matter though)

I would like to, if i knew what to do...

or choose different container.

BM card needs -r 23.976, and I don't think that is a high timebase...

TIA!
