I have a Samsung DVD-RW in a custom pc with xp. It will burn cds and play dvds but it won't burn dvds. under device mgr its listed as device type: DVD/cd-rom drive. but if I take it out and install it in another system with same op sys lists as DVD-RW drive and works well. It was working fine. When you inserted a blank DvD before it would autorun "Create DVD etc etc". Now it thinks blank DVD's are Blank CD's. It all happened between copys 2 and 3 of a "Make 3 copys" in nero 6 copy 2 came out great copy 3 got to 680mb then quit same brand DVD+R disk. Bought another brand new LG DVD-RW drive and its doing the same thing. I have uninstalled drivers and restarted. I have Downloaded drivers. I'm Stuck Help Please
