The Plextor 24X cannot burn SD 2.51.021 as of yet without some sort of assistance. I can burn a copy, use AWS and the new Betablocker, but then I'm forced to use it on my Plextor Drive with Hide CDR selected...which isn't good enough. If I need a crack, betablocker or Hide CDR media it isn't a 1:1. Like in the post above, Ollie will get us something (hopefully soon) that will do the job. In the mean time I just ordered a LiteOn LTD-163 and will try using it for the read and use my Plexi for the Write...I will post the results the second my drive arrives...hopefully Wednesday...I paid for FedEx 3 day which really means about a week
