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).
