Query: Will NOT play on many DVD players

Using MAC and iMovie to make home DVD movies. All played OK on a Magnavox MDV560 VR DVD player, but was intermittent (hangs) on a TOSHIBA SD-3800 DVD player. Thought player was bad. Purchased 2 more DVD players yesterday and got varying results but mostly bad - hanging or not recognizing the DVD at all. Switched to Maxell and so far all playing good with NO hangs.
