I recently received my MFSL 24K gold copy of "Dark Side Of The Moon" and, when I tried to play it in my RP91, I met with unexpected results. The player tries to read it in, but has a problem. After a few attempts at reading the disc and then some rather disconcerting sounds emanating from the player, it reads, "No Play." Have any of you RP91 owners met with similar results? Just to be sure that it wasn't a bad disc copy, I tried with a Sony Mastersound 24K gold disc, but to no avail. Now what???
