I've check the compatability lists and found that someone said the Verbatim DVD+RW works with the Samsung N-501, but it isn't on my unit. I've also tried multiple recording techniques. All DVD+Rs I've used do work, but I want to have a "testing" DVD and so far have been out of luck. The DVD+RW ReWritable organization website shows the N-501 as being compatable with DVD+RW. Can anyone help??

Thanks!
