plex's cant copy 2.51 and play them in another drive if copied using clone cd, without any weak sector fixes. this is a given. cdfreaks, who i consider the authority, says so. a software fix on the image is the only real option, as, once again, cdfreaks, in the review of the 40x plex, states that it is a chipset reason that safedisc 2.51 cannot be copied, and it cannot be fixed with a firmware update.
of course, everyone can be wrong
personally, screw u guys, i love my philips
