VidCoder

VidCoder is a DVD ripping and video transcoding application for Windows. It uses HandBrake as its encoding engine.
Calling directly into the HandBrake library gives it a more rich UI than the official HandBrake Windows GUI.

Two important things to note about running VidCoder. First and most importantly, you'll need .NET 4.0 (only the client profile is needed). If you don't have it, VidCoder will prompt you to download and install it.

VidCoder can rip DVDs but does not defeat the CSS encryption found in most commercial DVDs. AnyDVD is an excellent program that can remove DVD encryption on the fly. DVD Decrypter is a free option.

VidCoder is built on .NET 4.0 Client Profile/WPF in C#.

It runs on any OS that supports .NET 4.0: Windows 7, Vista, XP, Server 2003 and Server 2008.
