Weird but it doesnt:

Preparation:
chutz at lion tmp $ dd if=/dev/ieee1394/dv/host0/NTSC/in of=/tmp/out.dv bs=1M count=5
5+0 records in
5+0 records out

The following works:
chutz at lion tmp $ mplayer -demuxer 22 - < /tmp/out.dv

This one doesn't (which is almost what we need for playing a stream from the
device):
chutz at lion tmp $ cat /tmp/out.dv | mplayer -demuxer 22 -v -

MPlayer interrupted by signal 8 in module: demux_open
- MPlayer crashed by bad usage of CPU/FPU/RAM.
  Recompile MPlayer with --enable-debug and make a 'gdb' backtrace and
  disassembly. Details in DOCS/HTML/en/bugreports_what.html#bugreports_crash.
- MPlayer crashed. This shouldn't happen.
  It can be a bug in the MPlayer code _or_ in your drivers _or_ in your
  gcc version. If you think it's MPlayer's fault, please read
  DOCS/HTML/en/bugreports.html and follow the instructions there. We can't and
  won't help unless you provide this information when reporting a possible bug.
vo: x11 uninit called but X11 not inited..

Keep in mind, that I am aware that this is not a bugreport.
