DVD Writer unable to read DVDs ,reads only CDs

[blacklight]

@pimpom
If it was indeed caused due to improperly aligned lens , is it possible to restore the alignment back to original state?

Hi guys, me facing the same problem now.
I've two DVD writers (Ya, I don't believe any single company so bought two)
First: Samsung 203B SATA
2nd LiteOn IDE (model no. don't know)

Now, both of them have decided to betray me at d same time.
Samsung one Reads DVds but doesn't write and LiteOn writes DVds but doesn't read.

Sometimes both of them stop reading/writing DVDs.

I've cleaned the lense with lense cleaner. but it didn't work.
Oh, both of them reads CDs.

I had similar problem some months ago, its a lens problem

My DVD R/w is working with DVDs only, it does not senses any CD at all
