I have tried many types of media but I have still not managed to burn at 48x. I can get hold of a 100 pieces spindle with memorex 48x (blue and yellow type). On the media list, this media can be used with 48x. Have anyone tried it? I tried the Memorex 52x media made by Prodisc. Barely manged 32x without lots of errors.
I use the latest fw.
