Ah, Ha!  You've hit on the issue!

I'm trying to convert the stereo audio output from a 1/8" jack (e.g. iPod) 
to two RCA plugs to go into a switchbox. On the surface, it would seem that 
the shield should be the common connection between the two RCA plugs. Using 
the shield and one signal wire for one plug is OK but when I go to the 
second signal wire, I find that it's actually common to the shield itself. 
It doesn't seem right to leave the shield unconnected at this second plug 
but to connect it would seem to mean that now the two signal wires are 
shorted together. What's the story here?

What two devices are you connecting?
