Hello!
My pioneer can’t read dvd discs but can read CD-R discs.
What is the problem? Laser?
Last night i update a new firmware 1.58 and nothing.
Sorry for my bad english 
English is good 
Yup, its probably your lense.
You can gently clean it with a cotton swab and some rubbing alcohol.
Fire up Imgburn, then insert the media and watch the info window on the right side…
