Most likely if the laser will read cd's it's fine.

I disagree. Many DVD players now use a dual laser- infrared for CDs and
visible red for DVDs. It is very possible the DVD laser is failing and the
CD laser is good. Especially given that the DVD laser is far more likely to
have a lot of hours behind it and the CD laser will in many cases be
virtually unused on a DVD player.

Even on a single laser DVD player it may be possible that a bad laser
/optical block might cause a DVD disc to not play when a CD works fine as
the two formats place different demands on the optical block.
