With all due respect, I'm not sure what you'd like me to explain. I'm not sure what is causing this issue, or even what kind of televison it's hooked up to, or what kind of cable you're using; and even if I did, without being there, it's nearly impossible to determine.
My advice to anyone who is unhappy with their product to return it and get something that best fits your needs. I've always been very open about that on this forum.
Dear Mr. Samsung,
I'm on my second BDP-1500 in a month. Both had the same, exact problem. Intermittent sound drops. About every 5 or 10 minutes on both DVD and Blu-ray. My first player was shipped back to Samsung for repair. A week later, I received a remanufactured player (meaning, not my original) that wouldn't play anything at all. Luckily, I had a service plan at Best Buy and received a new, identical player from off the shelf. Goody, goody. Guess what, same problem. Even updated the firmware and still no dice. Intermittent sound dropping. What is the issue? Two machines later and still problems. Please explain?
