I'm new in the digital domain. Does it matter what type of coax cable is used for digital connection between DVD and AV receiver? I've never used the coax connectors before. I'm connecting DVD from home theater to a family room HT. Just installed Denon 3802 in family room and did not realize 5.1 etc effects need to be sent thru digital cable. I do have spare coax run between two rooms, some for initial cable signal no longer in use and also a spare monster quad sheilded coax for satellite signal distribution. Would either of these be appropriate?
