I have just bought a Yamaha HTR-5640RDS receiver to go with my Toshiba SD330 dvd player and want to connect them digitally. I have a co-axial lead but the only co-axial input I can find is for a CD player, the DVD input appears to be optical. Can I connect the two together using the co-axial lead and still get all the surround modes etc, I have tried this but receiver keeps defaulting to stereo for CD input. Am I being stupid or do I need an optical lead instead? How has everybody else connected theirs?
