Just did a slight overburn with my Plex 716A in the manner suggested by
zyzzle (CD-Speed - DVDDecrypter 18.104.22.168 - latest version).
CDSpeed suggested I could overburn the Verbatim 16X MCC 004 FFP by 152 Megs.
This burn is amovie created with DVDRebuilder Pro V0.79(Beta), which
came out about 10meg oversized. Normally, before I got the Plex, I would
have run the oversized movie through DVDShrink to "shave off" the excess
megs, but now, following zyzzle`s method (thanks zyzzle :)), I simply overburn.
Go on -try again
EDIT:btw, this burn was @16x.
