That's what I'm disagreeing with.

Say you have four <audio> elements, one for each dub, and a <video> 
element. All five come from different media resources.

I think you should be able to have them all in the group, but only have 
one <audio> playing at a time, ever though in each <audio> there is only 
one audio track and it is enabled.
