4x DVD-ROM reader needed

Hi,
I want to do on the fly backups of my dvd-r’s at 4x, I have a DVD-105 reader at the moment but it only reads the start of the disc at 2.52x which cause 4x on the fly backups to fail.

I use Nero to do the on the fly backups. Does any one do 4x on the fly backups successfully, if so what reader do you use?

Thanks :wink:
