Hi Marcus.

Thanks for the reply.

And here I thought I got the most when I bought the full featured
Nexus card :( In my case I will rarely use the MPEG-2 decoder to
Video out, but thought I give it a try anyway.

What is the problem/limitation with the NEXUS card ? Can I only
read one PID (video) as MPEG-2 or can I read 3 (audio/video/teletext)
or can I (as suggested) read 8 PIDs and can they be freely selected
among a/v/t and other types ?

When you say "the entire transponder" I assume you mean with the
same frequency and polarization. Right ?

Hmm, should have bought the NOVA card. Hope they don't stop
producing it. Are there any versions of the NOVA card to look out
for, or will any NOVA card version do ?

Kind regards
