We were talking about DVB hardware in general. 
The trend is to use dumber and cheaper hardware (no demux/decoder) 
on PCI cards and let the PC handle the rest.

You will find the newer DVB chips with multiple demuxes and decoders 
in the next generation of stand-alone set-top-boxes. 
Maybe some will also find their way on a PCI card. But there are no
such cards on the market yet.
