Optiarc AD-5170A disc reading problem



HI, I’ve had a search in the forum and cant find a response for my issue so thought i would try asking.

I have a 5170A writer which works flawlessly most of the time. A couple of weeks ago i picked up some cheap DVD+R DL’s which are Datawrite Titanium Branded.

With these discs i can burn them fine (CMC MAG-D04-000)
but when i then insert them into the same drive the activity light stays on and the drive basically hangs. If i pop the same disc into another drive (liteon) it plays fine…

Anyone aware of a way i can fix this so that the drive reads those discs? (I have tried just about every firmware out there and am currently on the LD 1.M1 modded firmware but it does the same)
