I have a DD/DTS reciever with only one optical input. It is currently occupied by my X-Box, which I also use as my DVD player. Right now I'm using the regular composite connection on the receiver for my PS2. Is it worth it to spend the money on an optical switch and two more cables so I can have digital audio with the PS2 also? Will the only benefit be from the few PS2 games that have DTS in the cut scenes? Thanks.
