Two factors, Alfa: One is that the MP3 audio standard is "compressed"--it offers less than the full range of movie and DVD soundtracks. The other is that computer speakers aren't full range. Youtube audio and video fidelity depends on the quality of the poster's audio and video source.
If you can hear what I am referring to, that at least is a relief. Maybe it is that. I know about compression, and CoDecs (Compression Decrompression), as well as lossless compression. I was under the impression that Mp3s were lossless. Looking up MP3s now, I can see that they are not lossless. Thanks. Now this means I need to seek out lossless files and re-download my faves.
