Well firstly i run my pc though a pretty cheapo stereo which two bi speakered speakers, but its a pretty basic stereo as i said. Now i just got a DVD player for my PC and the sound on the DVD's is so much better than mp3's, so is this all a dolby thing?

I didn't think dolby would make a difference unless you had like a 5.1 + set of speakers so whats the deal?

DVD audio is likely uncompressed. MP3s are compressed. Depending on the encoder and compression level, MP3s are not going to sound as good as the real thing.

To elaborate a little bit. When you compress an audio file, or any file for that matter, your losing information. As with any digital media, recordings are made by taking snapshots (samples are the technical name) of the media. Its very much like how a movie camera works. If you take your pictures fast enough. You can't really tell anything is missing when you play them back. In any event, when you compress a file, what you're doing boils down to taking fewer samples. Going back to the movie camera, you can take fewer and fewer shots which will use up less and less film but eventually you're going to start to see the image flicker and stutter. So while it isnt completely obvious, when your listening to compressed versus uncompressed audio, you're noticing the difference in the gaps between the samples.
