Slow Reading & Writing Speed - DVD RW NEC 2510A

I have just installed my NEC 2510A DVD writer and was making a backup copy of Terminator 2 movie using CloneDVD & AnyDVD.

The film is about 2h35m. Using Datesafe 8x DVD-R disc copying took approx 40mins to read and 50mins to write.

This seems very slow. I did have my DVD writer as the secondary slave at the time. I will change to secondary master to see if that makes a difference but I understand that it shouldn’t.

The firmware on dirve is version 2.15.

Any suggestions?
