睇唔到DVD??

i think need to reinstall driver

you should have a recovery driver disk with you, then boot the disk to reinstall driver.

or you can find out the model of the DVD rom, and go to its corresponding manufacturer's website to download thr driver.

good luck.

要安裝一些可對應 dvd 的播放程式，如media player 要下載某些功能才能播的。
