It's 2 different topics!!!!
The other one was how many mbs you can overburn a cd. in this one i want to know if you DONT overburn then how many mbs can you fit in a cd? i've heard that in a 800mb cd you cant really put 800 mbs, then my question was how many actual megs can you put on a 800mb cd without overburning!
The above text is a bit messy but try to understand.
