How to recognize the difference between Verbatim +R 16x made by CMC and Prodisc

Click on the picture here (taken from http://www.redflagdeals.com/forums/showthread.php?p=3976250):



The CMCs will have "Open" and "Lock" in Times New Roman.

LOCK OPEN = (CMC)
(I would tend to avoid PAP6 serials, personally)

LOCK OPEN = (prodisc)
(I tend to favour CMC Verbatim 16x dvd+rs, with the exception of the PAP6 serials)

You can also look at the serial in the inner clear hub of the DVD's. Prodisc serials have a + or - (+ since they're DVD+R's) in them. CMC serials often start with "PAPxxxxxxx".

Also ensure you're changing the booktype to "dvd-rom". Visit http://forum.slysoft.com/showthread.php?t=476
