I got a Pioneer 106 today and I'm using (Ritek dye) Ridata 4 speed media but I cannot get the discs to burn any faster than 2 speed using Nero or DVD Decrypter - does anyone know why?

Thanks all.

Try going to the Pioneer site and download the latest firmware for your burner. I have the same burner and I burn at 4x. I use Databank dvds and havnt had any probs so far but I think it is the firmware upgrade that is needed not the brand of blank disc.
