I haven't tested with burned cd's.
This speed increase happens everytime Itunes plays a regular audio cd.
I find it really strange. The only reasonable explanation is the the MBP's drive somehow isolates spinning noise better than the drive in the mini. On the other hand i find that unbelievable as no apparent spinning noise can be heard from the MBP when playing audio cd's.
To me it appears as if the mac mini simply spins the cd faster than the MBP. Again something that would make absolutely no sense.
Well, as I only use my mac mini as a media center, it would be really cool if I could restrict the rotation spped of the drive. Like I could tell it spin no more the 4x.
It is possible that something internal to the optical drive has offset and now the disc wobbles or something. Do you have iTunes import the cd while playing? That will cause quite a bit more activity noise from the drive itself.
It could be that the CD spin hole is not perfectly centered (happens a lot with cheap media) and the CD is vibrating more than it should.
A DVD should only play at 1X and would not be as prone to the wobble.
Try launching from your original install disk and run the Apple Hardware Test and see if that returns anything yummy.
