You will get transcoding effects. If you want to see what converting
from one lossy format to another lossy format does, do this:

Take a bmp or png of a highly detailed, very colourful image. A
photograph is a good test. Convert that to jpg. Convert that jpg to gif.
Compare that resultant gif to the original photograph.

Reverse the steps: convert the bmp to gif, then the gif to jpg.

Compare the jpg from the first conversion to the jpg of the second.
Compare the gif from the first conversion to the gif of the second. Any
differences you see (and there will be differences) are the results of
transcoding.

If all you have is mp3, leave it in that format. If all you have is ogg,
leave it in that format.

If you don't feel like listening to me:

% lame --decode file.mp3 - | oggenc -o file.ogg -
% mpg123 -w - monkeebutter.mp3 | oggenc -o monkee.ogg -

Add whatever options you want to oggenc. I find lame to be a better
decoder than mpg123 or xmms.
