Hi there, If you have a pretty new burner, it should burn both formats DVD-R and DVD+R If your burner is a few years old, be carefull, it might burn just DVD-R or just DVD+R. You can get all the info on your burner with tools like VSO Inspector, DVDInfoPro etc...
My burner will support both formats, I just wasn't sure if they could "talk" to one another, since they're opposites (you know, the 1's and 0's).
Thanks very much for your help! Have a good long weekend! (Whoops! Assuming you're in North America: USA July 4, Canada July 1) If no, well, try tipping one just because it's summer... Thanks again.
