Did a search, couldn't come up with any threads. I figured this goes in the Basics area.... The first stand alone player I bought know has problems with skipping after extended periods of play, or on just some discs. It'll begin hiccuping, and if you go back to the spot it had problems with, it won't repeat it. The same disc will play fine on my other player. Also, another weird anomaly, is that it once read CD-R's, but now won't at all. It's been in the bottom of the pile in my cabinet, and it's probably pretty dusty. Should I pull it out, give it a dust off, and use a lens cleaner? Or are lens cleaners just bogus, and the player is just exhibiting it's age? I was mainly looking at these: An Alsop, A Discwasher, maybe this more expensive one, which can do optimization tests, or this one. If lens cleaners are the answer, which of these would work for me?
