Software that can burn DL DVD as parallel track path

[toneman]

Does anybody know of any DVD burning software that can burn tracks onto a dual-layer DVD as parallel track path (as opposed to opposite track path)? I ask because the original DVD I'm trying to copy was laid out in PTP, and the burned copy (using Nero) is identified as having been burned as OTP...so is there something in Nero where I can force it to burn as PTP instead of OTP?

Thanks!
