R52, DLA, and iTunes

[cuppingmaster]

I've searched the Apple.com discussions for this, but nothing doing, so I thought maybe people in here could shed some light.

Ever since I've installed iTunes, I can't seem to burn anything using desktop burning software (DLA, RecordNow, etc). It'll start the burn, but then spit the disc right back out and say burning is unsuccessful. Strange thing is, I can rip and burn movies perfectly using DVD Shrink and DVD Decrypter. I suspected that perhaps it was the cheap BestBuy CD-Rs I bought, but after searching the Apple forums, I'm not convinced a Sony CD would work any better.

I have the Lenovo updater installed and keep hoping a drive firmware update comes out, but no such luck.

So the question is, does anyone have the same problem? And if so, have you remedied it? Or if you don't have the same problem, any ideas? I'm seriously stuck.

Thanks!
