Nd-3520a burning cdr's at only 8x or 16x

I can only burn my cdr’s at either 8x or 16x with nero 6.6 enterprise edition and disc juggler 4.0. I loaded liggy and dee’s 1.u6 firmware. How can i get it to burn at 48x? It’s not the media, the media is rated at 48x.

It actually was the cdr media. I put in a sony cdr and it would let me burn at 48x. I burned the other media at 48x on my old liteon cd-rw drive. Is there a way to make it burn at that speed with the 3520a?

Get rid of that crappy media.
