I brought the RP-56 home in December; it gets minimal play, NMT 3-4x a week, if that. No CDs are played in the unit. The first "symptom" was the "inability" to read the Sound&Vision test disk. Then last night I played a new-release DVD rental, and the disk drive began shuddering and vibrating the chassis top like the unit wud fall outa the rack! (mild exaggeration). After a while, and some pixelation, it settled down after a few brief dropouts. I dont know if I saved the sales receipt, but it's probably not worth it to me to send this away to a Panasonic repair center. I want a progressive scan for the future since I'm still using a non-HD, interlaced tv. So if the RP-56 falls apart -- hello RP-82 slimline. Not willing to give up on Panny no-chroma bug boxes yet.
