DVD Iso Extraction

[foobar2k]

Hi guys, just thought I'd get a few opinions.

What is the best tool to extract a single layer dvd to an .iso file. Alternatively, is there a good free tool out there for 1-1 single layer dvd copies?

I am talking about normal DVDs here not original Wii discs.

use "IMGBURN" or "DVD DECRYPTER", they're free and do the job...

Google on DVD Decrypter, can handle everything but is illegal.

The main reason I ask is for copying already backed up wii games (backing up my backups ;)). ImgBurn seems to get to 99% and then collapse.
