Allan,
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!
Johan

All,
I am looking at replacing my external DVB-S/FTA receiver with a dvb-s
card in my myth box.
As there is roughly US$100 difference in cost between the high-end
Nexus-s with hardware mpg2, and the low-end Twinhan/Skystar cards, I
would like to know what the CPU load difference is between the 2 types.
I understand that the low-end cards will have to split PID on the
transponder in software, but considering the stream is already mgp2, I
wonder how much work/cpu-load this really is. Does anyone have any
comparisons for these two type on roughly equivalent hardware?
I am running myth on an AMD64/2800+, which during all my myth-usage stays
in the lowest cpu speed of 1GHZ; recording with PVR-150 uses about 2-3%
cpu, playback on FX5200 card uses roughly 18% cpu; this makes for a
reasonably quiet system, and I'd like to keep it that way. (I do
transcoding and compiling 'after hours' and then it runs at full speed
and 'full noise' :-) )
Any information would be appreciated.
No difference at all. The Twinhan cards do (As far as I know) have
hardware PID filters. The "Fully featured" cards have a MPEG decoder on
board.
However, I have had poor experiences with Twinhan (specifically, the DVB-S
CI version) recently. You may be better trying to get hold of a
second-hand dvb-s card (Budget card) from ebay.
Cheers,
Allan.
