@samgar2 -- my Mohican also recently developed some skipping after 3 years. I noticed it seemed to lessen as the player warmed up about 1 hour.
Spoke to the dealer who thought it could be a lubrication issue, the laser mechanism rides on two rails as it moves along the disc and if it sticks, it'll skip.
So after powering up, I hit 'next' a few times, then 'prev' a few times and it goes away. This is just till they send some instructions on how to lube it, I'm reluctant to ship anything fragile and seems the repair facility is in need of being repaired.
