Thread: how come my dvd won't play on my laptop?

It plays through the DVD player/T.V fine.

Some one already recommend VLC player comes with it's own codecs should be able to run it on that media player , what is missing is a dvd decoder and they are not cheap to buy , check at corel and power dvd for their dvd decoder package , mainly all new laptops comes with a dvd decoder

If you want to stick to your default Media Player, you need to install external codecs like the free 'Windows 7 Codec Pack':

It's works on XP, Vista and 7.

A better alternative is to use a totally different but better media player called KMPlayer. It's free and can play any media format that you throw at it. It has all the codecs you need built-in:

Just read the installation instructions very well so you can decline the installation of the Ask Toolbar that comes bundled with most free programs. You don't need that.

it could be a problem with the dvd or your laptop
