I have just purchsed a new Poineer 510 dvd recorder, i copy my first movie from satellite to hard drive then made a dvd copy of the movie. It will play on my old Apex dvd player and on my pc player but will not play on my Initial DVD-9510 portable player... this player says it will play any type of dvd. I recorder to a dvd-r. If anyone can shed some light on this for me i would appreciate it. ( I am the newest of newbies )
