My bad, I meant both inputs.

If you just hooked both inputs to the output with a passive
Y cable, there's some chance that both sets of speakers
might work because digital outputs tend to be overbuilt and
digital inputs tend to be more sensitive than the bare
minimum.

If you used a video DA, both speaker digital inputs could
certainly be driven at the same time.

That would be the equipment and energy conservative way to
go.

Actually they have - a standard video switch and cabling
will do the job. SP/DIF and baseband video meet roughly the
same specs, especially when it comes to passive switches.

It might break your heart, the off-the-shelf < $50 video
switches and DAs from Radio Shack will do the job, and do it
well.

Tell you what, order them from me, and I'll be happy to mark
them up 1,000% so you can feel better.
