I currently have 2 DVD players hooked up to my DD/DTS receiver via Toslink cables. I just bought an X-Box that requires a Toslink cable for surround sound. The problem is I dont have an open fiber-optic input on my receiver. I would like to use a simple 2 way fiber-optic splitter from radio shack. Would this negatively affect the audio quality of 5.1 DD and DTS???
