How to ensure animation will play in ALL DVD players

I know this is slightly off topic, but how do I ensure my animation plays in all DVD players?

I am using DVD-R’s yet my animation will only play in one of my two DVD players. Does the codec come into play here?

What format and DVD type do the professionals use (e.g. Iron Man 2, or Cinderella)?

Thanks to all

What software are you using to burn your movie onto the DVD? This sounds like a problem that’s not related so much to what codec you output from our software, but rather how you’re getting that movie onto the disc. What options are you using in the software that you’re burning with?

Something else to be aware of is that if you’re using -Rs, there are some DVD players that take -R, some that take +R, and so your other DVD player may simply not read -Rs.
