There's nothing wrong with Roxio software, at least V7 & V7.5. Roxio's DragToDisk , in my experience, is by far the best packet writing software around & has never caused me any problems over the many years I've had in installed on my systems.
Nero's InCD & Sonic DLA are another matter all together & I wouldn't have them near my PCs.
For Sony to say you can only use Nero is absolute rubbish. Firstly they'll never know anyway & secondly it wouldn't stand up in law.
