Hopefully this doesn't sound too complicated, basically my question is this:

I download mp3s from the net and burn them as a DVD info disc (call it DVD-A) 

I delete the files off my computer then rip them from DVD-A back onto my computer
 
I then re-burn the ripped files onto another DVD (DVD-B) 
 
I delete the files off my computer again and then re-rip them back onto my computer from DVD-B
 
 
Ok so finally, are the files that are now re-ripped from DVD-B back onto my computer the same audio quality as they were when I downloaded them in the first place or no?
 
I know if this was cassettes we're talking about  the quality of the audio would be pretty messed up by that last step, but with MP3s I have no idea.

Do they remain MP3 files the whole time? If you are simply copying MP3 files from one disc to another, the quality will not change. If they are being converted into another format at any stage (inlcuding a temporary format) then they would suffer.
 
When you use the word "ripping" it suggests they are being converted.

No they stay MP3 files the entire time. When I said ripping I just meant putting them back onto my computer from the DVD I'd burned them on.

In theory just copying digital files around should make no difference to the quality.

Files don't degrade when you copy them digitally. However, if you burn mp3s to an audio cd and re-rip it, you apply the mp3 algorithm twice and thus you get degradation.

If you move a digital file all over the place, it shouldn't make a difference.
