Whats up guys...

I did a clean install of XP and now when I burn my DVD's (using IMG Tool and Nero) it is real slow, like 4 hrs to burn 4.3GB's whreras it took 30min before.
What the hell happened?

Any suggestions are appreciated.

BTW...
I'm ripping with DVD Decrypter
Encoding with DVD Shrink
Burning with IMG Tool
