Thanks! I´ve tried to do so, but my approach is not perfect at all. I know that it needs a little work.
And exactly the same goes for the pll library. Again I state: There are cards in DVB support that do not need it. The pll library lists 20 chips.
The one I have found out ensures pll reset for lgdt330x. The other 19, or at least a part of them (non-bt8xx boards as you already stated very correctly!), stand in question: Whether they are neccesary or not, and WHAT CARD they are serving for. Above the Pinnacle there MUST BE (This is an assumption!) more cards that do not need it. So I tried to beat a couple of flies by one simple catch. That's all I wanted to say.

Sure! I only wanted to start a discussion and put my approach into practice as good as I am capable to do. But I stated very clearly that it is not perfect at all. Up to now it's just a model, a very humble approach, a kind of self help for one proven case, nothing else. But I am missing the programmers practice to get it done "perfect".
Maybe there is someone around here to resolve that problem. So guys reading this: Please help if you can help!
The next step would be: Clear up the help files that tell the users what specific card type needs what specific frontend. So we could low down the risk of doing a mismatch selection towards 0 %! Wouldn't that be nice for everybody??
