I use it from 0.40 version and now in 0.46 it has changed a lot. It's developers add constantly more and more features. So now I can rip my DVDs in harddisk and create divx, xvid and ffmpeg movies with a lot of options (deinterlace, antialise, mp3, ac3 and more), with axcellent quality (HQ and fast resize) and WITHOUT delay of my sound. Now I wait the next version with subtitles and Ogg Vorbis support :) Do you want anything else? Two friends installed Linux only because of it,after their failure with Flaskmpeg, DVDx, Easydivx and others :))
With d5d and dvdnav plugins for new Xine 0.9.9, finally I have full dvd menu support in my Linux system!
