I don't know what's going on, but Nero, DVDInfoPro and DVD Identifier all refuse to read ATIPs on CD-Rs. I have an NEC ND-3500 and a USB IOMega 24X10X40. Neither seem to be able to read ATIPS. Any help?
Sounds like it's software related.CloneCD, AnyDVD and similar programs have options that can create this situation.
Indeed, it was. CD-RWin seems to have been the cause.
