My card is a WinTV Nova and I'm using driver version 2002-01-16 on
Suse-Linux 7.3 (kernel 2.4.10-4GB).
My real problem is: I want to stream the received TV-Station.
I've already tried some different methods of streaming (using
the files provided by the DVBVideoLAN Project, using the dvbstream-0.3,
using the Apple-Opensource-Streamingserver), but I never was able to
get a picture on a Windows-PC in the LAN. (dvbstream works fine, 
but the output can only be viewed on a linux-machine).

So I decided to use ffserver and ffmpeg. 
ffmpeg needs a tuned station on /dev/video, grabs it and sends the 
output to the ffserver, which streams it across the LAN (and I think
ffserver can get its input only via http from ffmpeg).
So i need a valid video-source at /dev/video.

Do you know a solution for this problem?

Thanks
Stephan
