Problems burning DVDs with LITE-ON DVDRW SOHW 1633S

Hello,
I’ve been trying all day to burn DVD’s using my external LITE-ON DVDRW SOHW 1633S. The problem I’m having is that it will burn one or two DVD’s with no issues whatever, but then it will continually have burn errors on 3 or 4 DVD’s in a row. I’m going through these expensive coasters quick. Can anyone help? I’ve even tried reducing my burn speed to 2X but no luck. I’ve attached my error log, which shows that “Device Not Available.” I dont get it. HELP!!!
