Well, no offense, but as a total Myth n00b, I had no problems  
configuring my PVR-150, which also had the options for Composite 0,  
Composite 1, S-Video 0, S-Video 1, Tuner 0, and Tuner 1. It's all  
about knowing what input you're using. If you're hooking your card  
directly to your cable line, satellite line (for those of you with  
DVB-S), or antenna, you use a tuner. Otherwise, if you're using a  
cable box, or a satellite box, THAT is doing the tuning, and you'd  
probably be better off using S-Video or Composite.

Basically: it's expected that you will know the terminology.

FYI: keep on your toes: Myth is dropping support for the PVR-350's  
MPEG-2 decoder.
