Yes, Len's advice has me wondering now. Do I have a dodgy cable? I will have
to change that tomorrow.

But more info. The old drive played DVD movies etc. OK, but slowly it became
worse until I couldn't read any one of them 9 times out of 10. CD play
back/burning was OK 100% all the time though - so I guessed the dvd laser
(whatever it does) was dead - hence why I bought a new one.

The new drive works perfectly, but for the udma33 issue. If it was the cable,
why would it read/burn CD OK, but not DVD sometimes on the old drive?
