Query: Unreliable.

I've had two of them. First one died exactly 365 days after purchase. Still played, just tried to load from every empty slot as well as the full ones, so it spent much of its time cycling rather than playing.Second one lasted longer, but now simply loads disk after disk and won't play any of them.My experience with microprocessor-based Sony gear is that sooner or later, their brains get scrambled, like the highend Sony cd player in my car, which is junk after only 18 months.I think I've bought my last Sony equipment, and would not recommend this unit.Other objections, even when it worked: long cycle time, noisy operation, size, clumsy interface.Good luck.
