My DVD ROM drive (Pioneer A103) acts strangely when I insert this DVD i bought (Region 1). It is a slot drive so when I insert this particular DVD it hesitates with a clicking sound as if some gears are slipping. And when it accepts the disc, it doesn't read it, and after a few more clicks it ejects the disc.

I have other DVD's (also region 1) which play perfectly in the drive. As do all of my VCD, data and music CD's.

What could be the problem?
