I recently made a dvd copy of our video TAPE family films for my sister. The dvd played on her stand alone. it did NOT play on my brother's stand alone. MY computer does NOT play home made dvds in any format finalized or not. The dvd was recorded on a PLUS RW NOT finalized as the manual suggested since that type of dvd is supposed to me more compatible with a variety of players. Another tape was found that was the original vhs tape I made of our films and slides from the 1940's to 1980's. The quality is not an issue. This time I was thinking of making 2 dvds, one PLUS RW FINALIZED if the unit will allow. and one on a MINUS RW FINALIZED if the unit will allow. Should I also use both a PLUS and MINUS SINGLE write discs? One of those 4 dvds should be recognized by his player and/or computer. Specific suggestions please. Please move as needed.
