Well, so far so bad... I burned the DVDs on my Panasonic DVD recorder. They play in my newer DVD players, but I cannot make a copy of them with Sonic DVD, Nero, or One click DVD. UNacceptable! I have used many types of DVDs, never had this happen. I guess I know why some DVDs I have purchased are playable, but not copiable.. it is the media! I will stick with Maxell,or TDK.
