Best software for ripping DVD's to AVI format with full Dolby 5.1

You’re right, Grant – no encoding.  That’s why it’s fast, of course.

In general the old “Good, Fast, Small” rule applies (pick any two).  Thus you can definitely use MakeMKV to make good, fast MKV files, but they won’t be small.  You can use other software to make small, fast MKV files but the quality won’t be any good.  And, of course, Handbrake produces great, small MKV files (at the cost of taking a few hours on a slow machine, although on my i7 I can generally do a DVD movie in around 30 minutes).

Quite frankly, anyone with a kid shouldn’t be scared of the AnyDVD (or DVDFab)/Handbrake combo – it’s FAR less complicated than raising a child .
