Hello- up til now i have had no reason to burn dvds. now i want to burn dvds. i have a nec 3540a tha burns cds very well - never any problems. i got some blank verbatim dvd+rw discs from my dad - i can't get the dvd burner to burn. it burns cds very well no problems. is my problem the media? i really don't know anything about dvd formats: dvd+ dvd- etc. what type of blank dvd will work and work well with the nec 3540a? thx!!
