>> i want to rip at full quality to re-edit<<
At full quality? It ain't gonna happen. You'll be taking highly compressed, multiplexed MPEG-2 footage and converting it into an editable format. It will NOT be the same quality as the DVD ... and especially NOT the same quality as the footage you shot originally.
DVDxDV and MPEG Streamclip are two programs you can use to convert a non-protected DVD's VOB files to editable formats. The format to convert to will depend on what editing software and settings within those programs you'll be using.
