Why wont media player play sound for the video

[spazos]

Hello, I burned a DVD on my home PC and it plays back fine with media player. When I try and play it back on a different PC, the sound doesn't work. Why won't it work?

Is this an actual DVD movie disc, or did you just burn a video file to the DVD because of its size?

What audio encoding did you use?

What version of Windows and Windows Media Player does the other PC have?
