Re: [Kaffeine-user] 'Can't tune dvb'...message

[<met...@da...>]

Well I did more searching and this is something I found on the Technisat
Glossar:
==========
Die Symbolrate bezieht sich auf MCPC- oder SCPC-Signale. Üblich für
MCPC-Kanäle ist eine Symbolrate von 27.500, SCPC-Kanäle arbeiten mit
Symbolraten zwischen 4.000 und 7.000.

 MCPC: Engl. Abkürzung für Multiple Channel Per Carrier.
Übertragungssystem, das für mehrere Kanäle nur einen Transponder benutzt.
(siehe auch SCPC)

 SCPC: Engl. Abkürzung für Single Channel Per Carrier Übertragungssystem
(digital oder analog), das auf einem Transponder einen separaten Träger
für jeden Kanal benutzt. (siehe auch MCPC).
=============
Sorry for those who can't read German...

It appears that I cannot receive the MCPC Channels

In terms of your suggestions:

LNB: It is a S/O LNB 10750 MHz and it seems correctly set-up in Kaffeine
since it receives the other signals.

In terms of tuning timeout: how do I increase the timeout?

Also If it is a driver issue where should I go? who writes the driver?

I use Kubuntu and I guess the driver was compiled in the kernel because I
just plugged in the PCI board and BOOM! it just worked!
