CD player vibration from CD's

I was changing a cd and noticed a strong vibration in my Oppo BD83SE cd player. I have had quite a few cd players and have never noticed this kind of vibration before. I found it was not caused by all cd's. With some, the majority, there is very little or no vibration. I am assuming the cd's in question are not round. Anyone else have this happen with your players? I am especially interested in Oppo Players but anyone feel free to chime in.

"Ddd1, Did you use a different Denon CDP of the same model and get different results? Or did you change players completely?"

The Denon was a DVD player. The players/transports that the same CDs didn't vibrate were different makes altogether. (ie. Simaudio Moon CD-1, CAL Delta, a couple expensive Sony universal players).

I'm not so sure the problem is discs that are a bit off-centered. I once had a Yamaha S1500 player that would do this vibrating on occasion. But when I bought a Pioneer DV-79AVi the same discs played perfectly.
My opinion: a design flaw in the Yamaha or just piss-poor tracking ability.

I noticed a similar vibration on my PC's DVD drive, may be a clamping mechanism, don't know for sure.

I have a CEC top load transport which I use a Herbies Grungebuster adhesive mat on the bottom of the CEC puck for damping.

A De Mat (Van Art Speak) rubber and carbon fiber impregnated mat is also placed on top of the CD to very great effect, but I would not recommend this one for tray loading transports or players, they could jam.
