If I start kaffeine, I get DVB-T to work. Kaffeine recognisez the card as:
Using DVB device 0:0 "Philips TDA10046H DVB-T"

Why TDA10046H instead of FMD1216ME?


TDA10046 is the channel decoder which is the "center of the frontend": Thats
correct.

Why is there no other device for DVB-S available?


Hm, does anybody know which channel decoder and tuner are used in the DVB-S
section?

Remember, we had this one on the video4linux-list.

It has a conventional DVB-S can tuner, likely covered by dvb-pll or easy
to add, at least all questions were asked.

The problem was the not yet supported tda10086 channel decoder.

This has changed and also no problems with the dual PCI bridge are
expected, except Mike took care to disable it ;)

Should be worth to dig it out.

Hi,
Are you referring to this thread?
https://www.redhat.com/mailman/private/video4linux-list/2006-August/msg00386.html
Just for clarification: My card is part of the Medion MD8386 PC, it's not the MD8800 Quad card.


no, I'm referring to Serdar Dere and the Medion CTX925_V.1 DVB-T/TV/DVB-S
http://marc.theaimsgroup.com/?l=linux-video&m=112033921222922&w=2


I also found this:
http://kernel.org/pub/linux/kernel/people/akpm/patches/2.6/2.6.18-rc7/2.6.18-rc7-mm1/broken-out/git-dvb.patch

but honestly I don't know how to aply that...


There are no patches yet, neither for the Medion Quad nor for your card
to get DVB-S working, but the components are likely supported.

In your case there are two saa7134 PCI bridges, which behave like two
seperate PCI cards in the special blue PCI slot.

The 16be:0005 bridge is assumed to handle DVB-S and has a tda10086ht
channel decoder and Andrew recently wrote support for it.

Your DVB-S tuner is labeled as SD1878/SHA. Should be the same like here.

And there were these patches recently to support it.
http://www.linuxtv.org/pipermail/linux-dvb/2006-January/007511.html

So this looks not bad, but maybe Hartmut can explain a little, what are
the difficulties with two PCI bridges and two frontends.

Cheers,
Hermann


Sorry, typo in Hartmut's address. Resent.


In this case, there should be no problem. The 2 PCI bridges make 2
logically separate cards (as long as there are no funny things with
the IRQ routing). If we have all components (channel decoder, tuner
and LNB controller) supported, we should have a close look.
