[linux-dvb] Mantis 2033 change tuner

[linux-dvb] Mantis 2033 change tuner

[Bas v.d. Wiel]

Hello all,
As I got no response to my question about changing tuner chips on Mantis
cards (I have one with chip ID 0x7d which I read about earlier), I started
experimenting with the sources from jusst.de. I changed mantis_dvb.c in a
crude way by simply copying the contents of a case statement for a Mantis
2040 to the one for the 2033 and commenting out the original 2033 block
that loads the tda10021.

To my surprise this compiled without any trouble and everything gets loaded
and recognized without error upon next bootup, including the tda10023.
However, as I expected, something crashes in a very bad way when I actually
try to use the tuner with dvb-scan. Am I doing something wrong? Or is my
card simply not supported (yet) by the mantis driver (too new maybe)?

Thanks in advance for any help!

Bas

Hi,

I don't own the card in question, but I am interesting in buying one if it works :-)

Hrm, 2040? Where did you find that case statement?

Otherwise, have you tried using the case statement for TERRATEC_CINERGY_C_PCI
instead? It looks exactly the same as the 2033 case apart from the tda10023
tuner. Perhaps try the attached (untested) patch?

Could you post the diff? Also make sure you have the latest mantis source code
(use "hg pull" + "hg up" to update).

Well, all my channels are encrypted, so...

But if you look at http://jusst.de/hg/mantis/, you can see that Manu has checked
in CA code today, only a couple of hours ago. And he's been checking in CA code
since a month ago. So apparently he's working on something right now.

Just my 2 cents worth: I have TwinHan DVB-C CAB-CI (Mantis 2033), and it
works quite well for unencrypted channels with provider INDI in
Flanders. I use Manu Abraham's latest driver.

Forget about encrypted channels, though. It's been roughly 1 1/2 years
since Manu promised a driver for this, but nothing has materialized so
far.

Sincerely,

Bob Deblier
