LG 8400B and TDK 48x CDRs

Anyone havin this problem same as me?

I have a LG 40x12x40 burner but I cant seem to burn TDK 48x CDRs at 40x.

Max speed i can get is at 24x.

any ideas or solutions ?

pls advise :smiley:

TDK does not make media, they re-label a variety of different media. Can you post the ATIP from the TDK discs? If you update your drive firmware, and the media still only offers 24x, then you are stuck with that.
