If your DVD players are older models 10 years or older they may have to have a specific DVD. DVD-R/-RW or DVD+R/+RW... newer players will play any type but the older ones were specific. DVD-R is the most common.
Or
It sounds like the DVD was not "finalized". This is the last step in making a DVD playable on most DVD players.
Most programs do this step automatically but once in a while it gets missed or isn't done properly. I would try again but make sure all other programs on your laptop are closed so nothing interferes with the DVD recording process.
Other possibility- if you used a stick on label on the DVD it can throw off the balance on some players. It's ok to use a Sharpie type pen to write on the DVD but stick on labels don't always work.
