This one works for Logitech Pro 9000, it uses very same driver as that

I have brand new Canon HFS100 and I can do basic things with kdenlive. 
But I found that I needed very latest x264 from source to do all 
exports, pre-combiled packages from sunab ppa were not enough, maybe it 
is just me here...

Dan and all other fine developers - is there something I can do as a 
kdenlive user?

And thank you for this great application. I do use kino, too, for 
another firewire camcorder.
