I was playing a dvd when all of the sudden the sound cut out for a second and then resumed. I rev the dvd to see if it was the dvd and the sound was present at the same spot it cut out on. I ignored it as a fluke but it happened several more times with more than 1 dvd. I checked all the connections and everything was okay. After playing a dvd to simulate the same occurrence the 4802 spontaneously rebooted . Has anyone heard of this before? This was a new machine purchased from GG last year so I'm surprised that this is happening. The only thing I can think of is that it has been hot lately and the unit is trying to prevent a problem by shutting its power, but my machine doesn't feel that hot to the touch and it can't be working that hard since I use external amps to power all speakers. Any suggestions would be helpful. Thanks.
