What spec establishes how well a cd player can play a scratched cd? With portable players, I figure this is a factor of how large the buffer is, but this is usually not listed in component-type cd players, or is it? I suppose it is also a factor of how well the technology used inside interpolates the missing/scratched section. Therefore, I'm presuming that the price of a good player is also something to consider - with the cheapies not being as good, I presume.

The reason I'm asking is because I'm trying to make usable copies of some of my scratched cds, but even after careful cleaning, they are still skipping. I figure that the cds are not repairable beyond what I've done with the cleaner, but I was hoping that there are players out there that would do a better job of reading scratched cds than what I'm currently using.
