problem on hybrid card that share same bus

Hi all,
I have just installed my hybrid card Hauppauge HVR-3000 (dvb-s, dvb-t,
analogic) with mfe drivers.

It works almost good under kaffeine, but I cannot
get totally work on mythtv under which I configured analogic and dvb-s, but I
cannot use dvb-t; that it is what I really need.
The problem is the operation
that follow the selection of DVB card, of few words I cannot select DVB Card
number as 1 (the only existing choice is 0..)
Reading information from kaffeine
configuration I think DVB0:0 is dvb-s, DVB0:1 is dvb-t.

If it is impossibile
use (under mythtv) 2 different cards that share the same bus, is at least
possible switch dvb-s and dvb-t? If yes, how?

I'm newbie and my english is
orrible, but please, anwer me!!

Thanks a lot, regards
-nicola

The way I got around this problem is to create some symlinks in /dev/dvb.
I have a udev rule that automatically links DVB0:1 to DVB1:0 - then to
Mythtv it looks like I have two DVB cards when actually there is only one.

So my real devices are:
/dev/dvb/adapter0/dvr0, dvr1, etc

and I have symlinks
/dev/dvb/adapter1/dvr0 -> adapter0/dvr1
/dev/dvb/adapter1/demux0 -> adapter0/demux1
etc..

(Or you could use the single front end patch for the HVR3000 then you
select whether you want DVB-T or DVB-S with a module parameter - but if
your card is working, I'd say the symlink approach is easier)

Robert.

Thank you very much Robert!!
I don't really know what is a "udev rule" (I'll
search for it..), but just I'll back home I'll try to create symbolic link as
you suggested!!
Another question: I don't understand, with this method, can I
use the dvb-s and dvb-t simultaneously?
(e.g record some dvb-s program while
watching dvb-t one?)
Another time, thanks

Have a look here (even mentions the HVR3000):

No, I think with the HVR-3000, the hardware is limited so that you can use
either DVB-S or DVB-T. Not both at the same time. I think (with the
latest drivers) it's possible to watch Analog + (one of) DVB-T/S but I've
never tried it.

Robert.

Re: problem on hybrid card that share same bus [In reply to]

Hi Robert, with your tips I can finally watch dvb-t, THANK YOU!!!!

But as I
told you, I'm not expert; at the beginning I created symlinks as you suggested
and the dvb-t card was working, so I didn't understood the udev relevance. Next
I reboot PC and all things become clear...

I also try to read the udev guide
that you indicate, but I can't complete understand it..
Sorry for boring, but
if you have the same card, can you forward me your udev rule or guide me in my
udev rule creation?

Reading the guide, this is something that you need (I
think...)

I'm no expert either!

I've also just realized that I'm not actually doing that anymore (I'm sure
I used to). All I'm doing now is renumbering my adapters which is the
example on that link I posted.

It might be easier for you to put some 'ln' commands in one of your
startup scripts (eg on my Gentoo install in /etc/conf.d/local.start) to
create the syslinks everytime you boot.

Unless someone who is better at udev rules than I am would care to help
out :-)

Robert.
