Movies I make via dvd shrink v 3 will not play on my $400 panasonic RP-91 but they play on a $30 Apex AD-1200. Movies will work on Panasonic if I use DVD decrypter to read and burn but then i can't re-author. Anyone know why ? I have a sony 510 burner and i use dvd+rw to test then dvd+r to burn. Panasonic is progressive scan so i would benefit from a better picture.
