The +/- formats are competition generated like the recent DVD contest which BlueRay won, or even farther back the beta vs VHS conflict. Today most DVD units read and/or write both formats. My most recent reading reported minus was the more prevalent of the two. Personally I do not like any RW to use for permanent storage. I have to at times use copied video, audio and text at work. Several times a year RWs which have been rewritten on several times fail; CD and DVD. Not too often, but they do fail. Without knowing what brand and model of DVD burner along with the software you intend to use, my initial position is as long as the disk is amendable you should be able to continue using it for additional storage.

Umm.is there a on/off switch on the back of the unit?If so try turning it off from there, for a good 30 seconds then turn it back on, and try it out.If you do not have the switch in the back try unplugging instead(this will sort of reset the unit).Then you can try again,also you may want to try another type of dvd-r disc (different brand),all of these dvd recorders no matter what brand seem to be picky the are returned a lot because people are just not informed, or in most cases have no patience.I have an electrohome dvd recorder and it seems to work well with the KODAK brand as of late dvd-r+,but 3 months ago the memorex brand and sony would work fine .lol.Good luck hope your unit is not defective.

Thank you very much for trying to help. After posting the "help", I've found a few tools that enable me to do this. Since I need to get this project done fairly quick (within 2 days), I went ahead and purchased the software from Corel: Ulead DVD MovieFactory 6 Plus. Now, I need to learn how to do this quickly. Again, thank you.

Move along dipstick. Nothing to see here.
