I'm afraid not. Only vls for linux has support for DVB

As far as  I know, the AIW  Radeon doesn't support DVB, or,  if it does,
I'm afraid it has no linux driver.  The only supported DVB cards are the
one supported by the linuxtv project.

Well, this  is possible, but  you'll need  several dvb cards.  Indeed, a
single dvb  card can only recieve  the chanels on a  same transponder at
once. That usually means something like 5-6 channels per card.

DVB streams  are usually 3-4 Mbit/s.  If you want to  decrease this, the
onlys solution is transcoding  (usually MPEG4 transcoding). Videolan can
do this. However, this is *very* power consuming. You'll need one recent
computer (something over P4 1,6 GHz) per channel.
