Noob question about NEC drives' DVD-R playback

I read it is a feature of the stock NEC firmware to play DVD-R discs in full speed (thus being noisy). Is it possible for patched firmware to enable 1x playback on DVD-Rs?

I’ve heard different.From what I’ve read it onlys reads at 6x max with stock firmware due to drive noise reasons.

You can try Nero DriveSpeed to lock the drive at 1x read.
