Playstation 2 game disc size problem

[yoyoma]

Ok, i've read this on a different forum, but I have both: Silent Scope, and Bust a Move for the PS2. I burned them both using CDRwin3.8c and Bust a Move was only 31.1 MB's, and Silent Scope was only 221 or something close.

I'm pretty sure that both of these games aren't that big, because based on my playstation copying experience, most of those games are at least 400 mb's, even if they are crap. So how do i get my burners to read ALL the MB's???

Thanks in advance
