I just purchased an lg bh200 online. It works great for the first hour. Then it will randomly lose sound. If I rewind a few seconds the sound comes back on and it will work properly again for 2-30 minutes. It does this with blu ray and hd DVD formats. Sd DVD plays just fine. It is hooked to my toshiba 65" dlp via hdmi then sound goes to my Bose lifestyle 28 series 2 via optical cable from my tv. I checked the firmware and it is the newest one.
