Don't know if this is the right place to put this, if it is in the wrong place, please move it. I got an Xbox and play/watch movies on my 30 inch HD Philips tv. Nice setup for the money. Now I finally retired my panasonic pro logic system and then got me a RCA Dolby 5.1 system. Not the fanciest, but with 400 watts it sounds incredible. I bought a plain old optical cable and hooked it up to my xbox (using the xbox hd pack to hook to my tv). Now everything is fine, but around an hour of playing a movie, the sound cuts out for a second and then comes back. I watched sleepy hollow and over half of star wars episode i today with my fiance, and it cut out twice. Now for over 4 hours of great entertainment, 2 seconds of no surround sound isn't much, but the cut out happens at key points, very irritating. Now when it happens I look at my rca receiver, the 6 indicators for the 6 speakers go off for a second and then all light up signaling 5.1 is in use again. It seems as though the xbox is periodically having a break in signal, or the optical cable is having a problem (first time using an optical cable). I would like this to be resolved soon because I just got into surround sound "land" and I like it and don't want any quirks. Has anybody had this problem and if you have, how was it solved? Thank you.
