I've search this forum but do not see an answer to my question so I'll post it: I've had my DVD burner (an external Pioneer drive sold by Cyclone)3 days now. Only one of the 2 disks that came with it was recognized, the DVD-R disk. I bought a couple of blank DVD-RW's (Imation brand) to experiment with. The first time I used MyDVD to copy a DV movie I used the DVD-R that came with the drive and everything worked fine. Now I am trying to use the DVD-RW's and MyDVD says that they are an incorrect format. Do DVD-RW's need to be formated (like a CD-RW does) or does MyDVD not support DVD-RW or am I doing something else wrong?
