I have a Sony DVPC660 5-disc DVD changer that is 1-1/2 years old. Purchased in 12/00. Has anyone heard of read problems with this model? It sure seems that if the DVD or CD surface is not perfectly clean, with no lint, dust, or smudges at all, then playback either skips or fails altogether. We have three or four CD's that just won't play because they skip or hangup, no matter how much I clean the CD. I know that it could be a damaged CD, but the frequency of this problem makes me think otherwise. It doesn't happen all the time, but much more than it should for a unit of this price (like 40% to 50% of the time). I have also heard that newer models may have a different type of read laser (red vs. green?) that may help correct this. Just wondering if there is any history before I pursue this with the store or Sony. You can probably tell I am not an expert, so if anyone can help, I would certainly appreciate it. Thanks!
