I'm planning on purchasing an Oppo DV-980H dvd player. Which connection is best for the audio: the optical digital or the 7.1 multi channel connections? I plan on hooking it up to a receiver that has the option for both. I've done a little research and from what I've read the multi channel connections are really only for DVD-audio or SACD discs. And not neccesary for regular movie DVDs. Is this true? I only watch movies and occasionally listen to music CDs. This is one of the reasons I'm getting this particular player, but if the multi channels are not necessary, then I'll look into buying a different model. I want to get the BEST possible surround sound from my movies. Thanks.
