Hi J�rgen, I applied your patch to CVS, thanks for your driver.

Also got this card from dvb-shop a few weeks ago, strange to hear that it should be an old prototype.
The patch below is working fine with my card, but I am not an expert in linux driver programming, so maybe some changes have to be made. I also have a patch for the oldstruct driver, so if somebody needs it let me know.
Next problem for me is now, that some channels move to VHF in Berlin and I don't know, if this card is also working with VHF. Does anybody know more about this?

+This tuner module needs the file "Sc_main.mc" from the windows driver.
+It should be copied to "/usr/lib/DVB/driver/frontends". Or give the
+module parameter: mcfile="/PATH/FILENAME". The microcode from this file has +to be loaded only once after a power on. Because this takes some +time, you can pass the module parameter: loadcode=0 if you only want to +reload the dvb driver.
+This driver is working fine on my computer, but I am not a real expert for
+linux modules. So I hope somebody else, who knows more about linux programming
+and dvb frontends, will do some work an this driver.
