Just to let anyone who dosen't know, there;s 2 different dvd recorders- plus & minus. minus being the most popular in the DVD players. I copy movies & only movies copied in RW- will work on the 4 dvd players i have. The neighbor does his in RW+ & we can't play each others dvds. of course, as long as you're recording & watching on the same unit it wont make a difference. Theres the chance though it wont play on other dvd units.
