Hello, ive bought this drive about 1 week ago. Burned loads of DVD+/-Rs (about 20). Now when i put any type of DVD disc (blank or not) it almost freezes my PC (AMD Athlon XP 2400 w/ 512mb ram) I have tried real Movies, Backups on DVD-R and DVD+R but it does the same thing. When i insert real CDs or CD-R/W it works. What is the problem here? I have checked all cables etc. Everything seems to be fine. Is this a software or firmware error or something?
