AFAIK, some people on the list are working on that.

Only the DVB-s card gives you an uncompressed stream, because it has
an MPEG decoder. The Nova just delivers the stream from the satellite.
ffmpeg works with the DVB-s and you can use get_http from the
mpegtools to receive it and pipe the output somewhere else.
With the Nova card you could try to combine ts2ps and the part of
ffmpeg that sends data to ffserver to serve an MPEG program
stream. Should not be too hard, but you would have to study the ffmpeg
and ffserver code.
