My old HTIB's DVD player is dieing. The tray won't stay open. It just opens and then closes right back. I am OK, for now, with the sound it puts out, so I would rather not replace it right now. However it only has one digital input. If I get a blu-ray player to replace the DVD playing aspect of it I need another digital input. Do they make optical or coax switches that automatically switchs to the one that currently has sound on it or that are remote controlled, ie. I don't want to manually have to switch it? Also what would happen if I just run two digital coax signals into a reverse splitter with 2 in and 1 out? Would it work? Seems like it would, but it is way to simple and cheap to work.
