[arch-general] ConvertXToDVD alternative for Linux.

Hi, One of the very few reasons that I still Dual boot windows is that I don't know how to convert media files from one format to another in Linux. On windows I use 2 very easy to use softwares namely FormatFactory and ConvertXToDVD for my needs. Can you guys tell me about any Linux alternative to that? I tried installing ConvertXtoDVD using wine. The main program installs fine but the DVD menu templates, though installed, aren't detected by the program and hence I cant use the DVD menus. Thanks.
