Playing DVDs on a computer requires a method of decoding MPEG-2 videos. Most of the time, DVD decoders are provided through software, and many times DVD decoding is supported by hardware on your video card.

If one application does not work, try installing another DVD player application on your computer. It's quite possible that the DVD decoder is having problems.

Sometimes your video card (adapter) comes with software to play DVDs.

Outcome

You are able to play DVDs on your computer.
