Input from demux (not dvr)

Hi,

There has been a change recently in v4l-dvb allowing to send the output of a filter to the demux 
keeping the TS nature of the stream.

I personally think that it would be very interesting to be able to run mplayer from the demux so 
that one can have multiple instance running at the same time.

It goes without saying that there is only 1 frequency.

Still it is possible to set only 1 filter per demux, so to watch video+audio one has to get the 
whole TS and select via -aid and -vid.

1) is it possible to set a filter "per program".
2) would it be worth extending the demux driver in kernel to take more that 1 pid per filter?

Anybody interested?
