The K1+ has Dolby/AC3 internal decoding.
The Pi2 project was an interesting project for a few of us, but it required excessive Linux knowledge and time to compile. No simple automatic updating from a repository. Even after waiting for hours to compile, it was 50/50 chance if it would even work. Then a few weeks later a Linux update would disable. I gave up trying to maintain the PI2 for DVBS and installed OpenElec for media center operation. Definitely a project for a Linux guru, but not a simple solution for an average satellite hobbyist looking for a solution to easily install and maintain.
What I took away from the Pi2 project was how wonderfully easy my PC based HTPC was to install, set-up and use!
Hard to beat a PC with a PCIe DVBS2 tuner card running EBSpro and VLC! It just works!
