I've been encountering some strange reading problems with my new NEC 3500A. It reads most of the DVDs perfectly (including many scratched up ones). However, it refuses to play, or even recognize certain DVDs (each of the DVDs are different, not limited to any particular brand).
The strange part is, these DVDs are in immaculate condition, and play perfectly on my PS2.
My drive's housed in a Plumax USB2.0 External enclosure. Any idea what may be causing the problem?
