output: It's 64 Studio, gus3. It has all the same audio and video apps you can put on any Linux; what sets it apart is it's very stable and fast, and it has all the low-latency kernel tweaks you need for good computer audio. I don't know if there are any specialty Linux apps for digitizing legacy media; I use Audacity. http://www.64studio.com/
