Once or twice a week I'll be watching a recorded program, and my 5504 will get stuck, repeating the same from an a fraction of a second of audio over and over. It will do this for about a minute, and then finally reboot.
This sounds like it may be the disk corruption problem mentioned on Mikeyboy's site. But after it reboots, I can play the same show just fine, so I don't think it's a bad spot in that file. I also think it has happened when I was watching a show streaming from a networked RTV.
Does this sound like a power supply problem?
