"codec" is just "coder/decoder", or in other words, a software
system which can translate input to a new form, and then translate
back.

Vorbis is a lossy codec, which means that the translation cycle
gets you only an approximation of the original input.

Depends on how much storage space you are willing to use.  You could
make lossless copies of the original sources which would move them
from the "never again" category to the "always available" category.

If you can't afford a spool of blank CD-R's, then yeah, I suppose
this would work too. :)
