I am quite familiar with backing up my Blu Ray collection to MKV for easy storage on hard drive (and keeping my originals in good condition). However I am now moving into the backup of my 3D movies, of which I currently only have one - AVATAR! - but I encountered a screen that I am not familiar with in AnyDVD HD...

I followed the advice presented and decided to rip the movie to hard drive as an image. However now I am wondering where to start with regard to converting to an MKV and retaining the 3D aspect.
Thanks for your suggestion. I am already using this program, and am pleased to report that it worked very well for the conversion of my Avatar 3D. This program could probably be improved slightly in the area of sub-titles. Currently it only supports two "modes", hard-subs (for everything spoken in a movie...), and a separate SUBs file. Unfortunately in the case of Avatar I only wanted sub-titles for the parts where the aliens speak their native tongue, not for all talking in the movie, as a result I settled on no sub-titles.
