Play it in your laptop and see if it works: Probably does. There are settings you can tweak to make it more likely to be read on a DVD player, but computer ones tend to be better at figuring out what's missing/wrong and fixing it on the fly - if a DVD player encounters an error it tends to just fall over. If it encounters something slightly different from what it expects it falls over. It varies from player to player and manufacturer to manufacturer.
Have a look at the options on recording, try the disc in different (other people's) machines, if you have a laptop play it through that...
