I've read that some people place warped records between sheets of glass and leave them in direct sunlight, or even in the oven at low temperatures. Never tried it, though I do have my fair share of warped records. You're right, though, they're still quiet.

There is a record warp repair device out now. Basically, you put the LP in the device, which has a flat metal base and lid. It heats gradually, then cools down...warps are gone. Cost is about $1700, IIRC.
Use a reflex clamp if these are dish warps and your spindle is tall enough for a clamp to grab. As horrified as I've been with how I've found some of my purchases stored, I have hardly any warped records.

Damnit, sorry to get off topic. Warped records are the worst, i have a Dave Matthews Band "Before these crowded streets" on vinyl and it's warped. Not sure how the hell it got warped, because it played fine the first few times, then i tried to listen to it a few months later and it was warped. It's rare too.
