The Dc20-driver is free, because it is in beta state.
The DC30-driver is not free, becuase I spend a lot of time and money in my support and developing new drivers.
For this I need a return service for future drivers.
Im make all privat, this has nothing to do with Pinnacle!
I think 10 EURO is not much for a card which cost (a few days back) 500 to 1000 EURO.
The next driver will combine driver 1.5 and WDM2.0.
I hope it will be ready after summer (if I have more time)
DC30 is a very good-card if you see the current USB-devices.
The quality of Dc30 is great and also the high datarate.
