SATA optical drives

Hey all My name is Michael. I have a question regarding SATA DVD Drives. I have just installed one in a new computer. I am getting sound when I put a music cd in the drive, but when I play a DVD movie there is no sound. Has anyone run accross this before?

You need to install an mpeg2/ac3 codec.

Try with VLC tool.

What program are you using to play the movie? If you have a sound card does it have a plug that you can plug the output sound on the drive to connect to the sound card?
