thanks for the feedback. I had not carefully looked at the nexus-s hardware,
and now see indeed the mpeg2 decoder; as I play via an fx5200 card, I won't
need this and anyway, it doesn't look like it's supported as a fb-device
like the pvr-350.
When you say 'second-hand dvb-s card (Budget card) ', do you mean the
Skystar type cards?
What about the new Twinhan 102G, is that supported by the DST drivers?
Thanks a bunch!
