The PC is for me as well - I run a Lenovo ThinkCentre tiny through a Yamaha MD8 MiniDisc multi-track recorder which then goes into my Yamaha 5.1 receiver. The MD8 is used for karaoke, and the receiver uses Dolby ProLogic to make it surround.

For recording MDs I use a Sony MZ-N920 with Web MiniDisc Pro.
