UPDATE 2019: DVDInfo is offline. For converting DVDs and Blu-ray disks to an open format I would suggest MakeMKV.
Ever wanted to rip a DVD with Mencoder? You would then need to find the right title number, the right subtitle track and and audio channel ID. With DVDInfo this has been made really easy. Just run DVDInfo, and it will find the longest title on the DVD and display all audio and subtitle IDs, together with the language and audio format. With this tool, you can spend less time tweaking, and more time watching movies!
