The german program works waaay better since it actually resets the speed each time you change media. Plus, its even in english after you install it.
It is truely shocking how much noise these things make at 48x, and how utterly silent they are at anything below 16x. Way way better for watching movies, and since you can set it per drive, I can use my CDRW to read stuff and absurdly fast as possible.
Not to mention CDs are recognized way faster, and everything just seems to load faster, as it isnt constantly going back and forth spinning up and down.
