Philips cd-i - skipping and crashing on a game with no visible scratches or scuffs

[WindowsKiller]

I know this problem, which more or less only affects FMV games and audio/video CDs (more general: everything that constantly streams data from the disc). However, I only experienced it on CDM12-equipped CD-i 210s. It's cause by the grease drying out, so that the laser can no longer move fluidly and often lose tracking. Re-grease will fix it. Owning a 370 myself, I can tell you that this won't be an easy task, though.
