[linux-dvb] Mantis 2033 dvb-tuning problems

Hi,

I have got a Twinhan vp-2033 based card. I run Ubuntu 8.04. I have downloaded the driver from http://jusst.de/hg/mantis and it compiled just fine. But when i try to tune a channel the tuning fails. It is a newer card with the tda10023 tuner but when the driver loads it uses the tda10021. What do I have to do to make it use the right tuner? Can i give some options when compiling or when loading the module?

dmesg gives>

Try the attached patch which fixes this for my Azurewave AD-CP300 (at 
least last time I compiled it).

I've sent it to Manu and he was going to apply it, but it hasn't shown 
up on http://jusst.de/hg/mantis/ yet...

Fix tda10021 to not claim tda10023.

Previously mantis_frontend_init() relied on the PCI ID alone, this
causes trouble when a card has a different chip depending on
the manufacturing date. This match makes it work with newer
Azurewave AD-CP300 cards while (hopefully) maintaining compatibility
with older cards.

I tried your patch, and it "improve" things a bit. Kaffeine is able to scan
a few channels now without any entries in /var/log/messages. w_scan finds a
few frequencies, but no services. Scan results are different between scans.
w_scan works "better" if timeout settings are increased.

The channels found by Kaffeine are not viewable, there is something moving,
but I guess the driver is unable to descramble the signal. 

My system is an Ubuntu 8.10 amd64. The network is ComHem and the CI is from
Conax. I also have the AzureWave AD-CP300.

Since this is an improvement I agree with you, Manu should apply the patch.

Hi,

this sounds like exactly my problem! I have a TwinHan / AzureWave
AD-CP400 CI DVB-C
with a Conax CA module and I'm using the ComHem network also. Will try
out the patch soon!

I don't know which tuner is in the CP400 but this is what it detects:

I'm running it on the Debian 2.6.18 kernel, viewing free channels (our 
provider Kommunicera gives us the standard channels via analog and 
unencrypted DVB-C).

Scanning still sucks for me, but since I did the initial scan using a 
borrowed DVB-C card (something 1500 something) I'm happy for the 
moment. It would be nice if scanning worked tho, then I might be able 
to run myth-setup to completion (currently I use mplayer combined with 
at to record programs).

I'd suggest you find someone that can provide you with a 
ComHem channels.conf to circumvent the scanning problem for now...

He said he will, I suspect he's just not had the time to do it.
