Mantis 2033 change tuner

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).

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

Hi,

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.
