Some people use their power tools with a buffing attachment.

I've seen these kinds of methods discussed on various forums, along with references to all kinds of random polishes and cleaning products -- from toothpaste to peanut butter to Brasso. But if a damaged disc is really worth the effort and/or expense of a repair, then it's worth doing with a proper method. And that doesn't include home power tools, items from under the kitchen sink, or something you'd more often spread on toast. Honestly, those methods are rather idiotic, and not at all suggested if you really want the disc to be recovered. I'm somewhat reminded of sad incidents where somebody has ingested rubbing alcohol (and often died) because he/she wanted to "get drunk" and not understood that not all alcohol is the same. The same wisdom applies here. Not all buffing tools and cleaning products are equal, and meant to be used in just any scenario. Discs are fragile and touchy, and this sort of unorthodox cleaning method is considered to be mishandling and misuse -- i.e., user error. By no coincidence, it's generally user error that caused this entire damaged disc scenario.

You can read highly technical tests of these types

When it comes to authoritative information on disc testing and error correction, I'd actually suggest reading some of the white papers from Mitsubishi, Pioneer and DaTARIUS. Of course, the main issue with these documents is they can be hard to find (especially the older MCC and PVC docs), and are really not all that accessible to the layman due to excessive jargon and optical engineering concepts.

I believe they are based on Reed-Solomon codes

Correct. This is addressed in quite a bit of detail in Jim Taylor's DVD Demystified (the book, not the free website). If you're truly interested in advanced information on DVD, and are interested in something a little more authoritative than random websites, then it's worth the
$33 from Amazon. (Of course, I have found some errors on his site, so even he's not immune to errors. But it's still better than a lot of the usual places, including wikipedia and certain popular-but-amateur forums.)

ps could you comment on my entry to the disc labelling FAQ? I put a lot of research into that. Short answer, disc labels are actually OK and the weight doesn't make it wobble. The problem lies in the tension added by the label; if too stiff it pulls the disc back towards the center which makes it wobble.

It was just replied to by staff.
