Frantisek,

I thought that would be the case - i.e. it is possible to receive the stream 
but that hardware MPEG decoder on the Siemens card would be unable to display 
the signal.  What is the maximum bit-rate that the Siemens card can deliver?

At least on my PC I use for satellite (a 300 MHZ Pentium), a software decoder 
would stuggle.  Does anyone know if any of the MPEG2 decoder cards available 
(preferably with linux drivers - e.g. the KFIR encoder/decoder?) can handle 
these streams?

Please let me know if I can do anything to help with your experiments.

Best wishes,

Dave.
