hi
i mean Parallel Track Path. i seem to remember a thread in a lost forum about navigation discs and the problem then was the original disc was ptp , dual layer+r media is otp, Opposite Track Path.
i cant remember the outcome of this , i was just trying to find out if the original was ptp
That's the thread I remember too mate - I am 99% certain that in the end we discovered that the disc was PTP and thus not able to be backed up.
