I just received the DTS version of Toy Story laserdisc, and i have my CLD-D703 hooked up through a digital coax cable to my receiver, which is a Sony STR-DE895. For some reason i don't get any sound at all, and i even tried hooking it up using a TOSlink optical cable. Am i supposed to select something on my receiver or laserdisc player? I have the settings at Auto instead of PCM, and i can get DTS and DD from my dvd's. Please help!
