I've been spending weeks trying diffrents kernel versions, bttv and dvb 
sources : nothing !


I'm quite sure it comes from the communication beetwen I2C and  DST via 
the BTxxx stuff. But where ??? i don't see. I've managed to drive ONCE 
(only lol) an Hercules SmartTV but i can't reproduce the way i did it. 
I'd like to know exactly how to setup a DST CLONE card to setup a fully 
operational DVB Linux box for any Twinhan card.

I'm still searching for a solution. Any help is really ... really 
appreciated.


Thanks for reading
