[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>

Any ideas?
