DV Live Playback (No Capture) Under Linux

[Maltheus]

I want to use my Canopus ADVC-100 capture device as a way of viewing my satellite feed on my HTPC in Linux. I can capture DV using 'dvgrab' and play it with mplayer, but I can't do this for some reason:

dvgrab - | mplayer -

or:

dvgrab --format raw | mplayer -demuxer rawdv

It either crashes or simply doesn't show anything. I can capture to a file, and then playback that file while capturing (only if specifying raw dv format), but it only plays up to the point it's captured to at the time I start mplayer.

Is there anyway to treat the DV source as a Video for Linux source, allowing me to use:

mplayer dvb://

Or are there any other applications better suited for this? Thanks.

Have you tried with a fake file in between, i.e. by using mkfifo?
As suggested by Tobias here (http://forum.doom9.org/showthread.php?t=121700).

Yeah, actually I have. It's like come sort of header information needs to be written or something, before mplayer will recognize the whole thing.
