flanger,

Since you're into stabs in the dark, here is mine: If your drive seems to
be changing speeds a lot (spinning quickly and then spinning slowly), a dirty
lens might be the cause, in which case a couple passes with a cleaning CD
would fix it. If spin-up problems such as this occur with certain discs only,
the data on the disc may be to blame. Certain types of copy protection make
deliberate errors on the disc, which may be confusing your drive. There isn't
much you can do about this, however.

Any other guesses?
