yup! MP3's only hold a fraction of the Original Music when it is encoding the MP3.

hmm
.. lets say that the Original Audio was a song you liked off of that CD.
.. lets say that the MP3 Encode removed about 70% of the sound information.
now you want to re-create the Original Audio from the 30% leftover in the MP3.
.. lets say that your new MP3 looses 70% of that original 30% it started with.
What do we have left of the Original Audio ... 18% ??
.. these are just random numbers that I'm using here but they are trying to express why your MP3 can not become the Original Audio Again. MP3 is a Lossy Compression Format. Nothing Compressed can be totally UnCompressed -- its called a "lossy format" because a good portion of the information "will be lost."

(if not, how to avoid it?)
Use the Audio recorded from your CD's Directly to your AMV -- no sound lost if every thing is Direct.

hope that helps a little in explaining your Compression issues
