HELP!! Plextor 712A and Microstudio 2.613

[TrekStar]

I have a 712A DVD-USB and everything works fine in Microstudio 2.613 until I try to make a copy?!? It goes through it's routine just fine, and says it's coppied and ejects the disk! But when I try to play it, I get nothing! Went to Plextor and downloaded sofware...But nothing!?! Also, when I got this drive with my software, It didn't come in a box. Just the end flaps. Is this the way everybody gets'em? The instructions have a picture of a nice sleek unit, But mine is a big ugly silver box that I don't know how to even open to do a self-test Diagnostics?? This is a internal drive inside a aftermarket box from "Bytecc". One last thing...If I buy a Plextor off the internet somewhere else that says it will do CG+G's, Will it work with MTU's Hoster and the like? as I have all the programs from MTU! I have spent four days trying to debug this #$%%^ and I've just about given up!! Help, Bruce
