Well, I'm having exactly the same problem. Device Buffer at 0%, and never moves from there. I'm using Vista, but the 32-bit version. I used to have XP SP2, and had the chance to make a burn, but since having Vista, I could not even make one burn. You could say its Vista, but I'd made a research and found out lots of guys that have Vista, and my drive (Samsung SH-S182M) have it fully functioning. I have the latest firmware also. So, theres some program, o some driver, o i dont know thats causing this. Hope someone who reads this, had the same problem and could solve it, because i really dont want format my pc
