I tried the additional GPIO2 control, but it didn't help  - I still get the 
message, that no frontend was found.
I am not sure if the card does either video or dvb mode - For video input it 
has an S-VHS connector.

The i2cdetect data hasn't changed with the GPIO2 control, too.

I wasn't able to spot an stv0299b-chipset on the card, but this may be, 
because of the closed tuner-box, so I can't look into it.
