CRC error on NEC 3500A

I just purchased a NEC 3500A, and have 1.05 firmware. but i can’t get it to read some DVD’s some old ones and some brand new ones with no scratches or anything wrong with them. the new DVD worked fine on a DVD burner i used at another location, i"m pretty new to ripping and burning does anyone have any thoughts? Thanks :sad:

Read the media slower. Use Nero Drivespeed.
