I'm not sure why the ps3 browser won't scroll down the rest of the web page; it works on all pc browsers ok. The site contains a flash swf file (as3), some small pictures and a little text. Other than that its just html, css, and js(for swf file embedding).
It doesn't scroll because you have this:
body {
height: 100%;
margin: 0;
overflow: hidden;
padding: 0;
}
Which hides the scrollbars, to fix this remove overflow:hidden
