possible? i was wondering: almost ALL DVDR/RW/CDR/RW-and-whatever-other-extension-exists have these little plastic bits that should prevent the CD from falling off the tray if the drive is mounted vertically instead of horizontally. has anyone experience with this and can tell me if this method sucks (too much hassle when inserting a cd and such)? doesn't the PS2 unse these little things too if placed vertically?
