DVD-RW Drive not recognizing a DVD+R disc
I am having trouble burning DVD+R disc's. My OS is vista and i have used this burner and these same discs in the past. I haven't had the need to do so in months and now that i come back to create some backups my DVD/RW drive doesn't recognize a brand new DVD+R disc. These disc are the same ones i have used in the past(Same Pack even). Anyone have any idea what this might be. Maybe a vista upgrade or something that i downloaded in the last few months that could have thrown something off?
