Pioneer 108 CD burning Problem

I just brought a Pioneer 108, I upgraded its firmware from 1.04 to 1.06
I have the latest nero installed 6.3.1.17

The problem is, the drive would have problem writting any speed faster than 16x for cd.
I already maxed up the ultrabuffer and the cache.

The writting process will fail if i burn at 24x or 32x 40x.

Does anyone else have this problem? and how do you fix this problem?

I know I can just burn at 16x but I would like for it to function as it says it would.

Thanks

there’s another update out for nero mate 6.3.1.20
it works ok for me with that version
Id try that first.
good luck

Thanks,

Guess my nero is not the latest. I’m downloading it and I will try it.
