I've used Fair Use Wizard a few times. The commercial version lets you download and use it for free unless you want output to be larger than 700mb...then you have to pay for the program.
I used the celtic-druid version which is no longer up to date. It had no restrictions on output.
The only thing about Fair Use Wizard is that you have to work straight from the disk or from a ISO of the disk. It doesn't work from files in a Video_TS folder on the hard drive.
Quality is pretty good.
