This.

I'm going to try it with another drive first, I think this is a firmware problem with the 716.

I have confirmed that PX-716SA has a firmware bug, FatArnold also has a PX-716A.

XTac Had same safedisc issue with PX-760a and an OEM version of Need For Speed Porsche 2000. Disc dumped fine with premium.

/vn Search specific bytes
What does that mean? It shouldn't insert bytes, it should be treated like a forced offset. /vn 18032 should be equal to /a -4508.
And 18032 should be the default value (if no value is set after "/vn").

I'll fix it like this
Code: Select all

No.
I created PVDTools(
https://github.com/saramibreak/PVDTools ) to decode VideoNow disc.
Please decode your VideoNow disc, using this tool.
Some reasons, VideoNow player may require 18032 zero bytes in the head of the 1st track, but it is obvious that "e1 e1 e1 01 e1 e1 e1 00" (black&white disc) is the head of the 1st track as the disc format.

Could you explain that? What offset should be used for the B&W discs, for the Color discs, for the Jr. discs, for the XP discs?
