Audio discs have different focus requirements ( 650MB vs 4.7 GB in
capacity) as the data is packed more dense. The lense might have small
dust particle which prevents reading dvds but does not matter for cds.

The drive has two lasers. One for CD and another for DVD. With 6X the data
in the same space its not surprising the DVD is usually the one to go.

If th OP is saying it will read data DVD but not a video DVD, it could be a
codec or other softwar problem.
