Convert any video to DVD in Ubuntu

Question

Actually, I'm looking for alternatives for ConvertXToDVD that works on Ubuntu.

Requirements:

• Convert various video formats (.avi,.mp4...) to a format that's readable on a DVD player;
• Add subtitles and change the text format (font,color,screen position) for them;
• Customize chapters;
• Create menus with custom options and background sound;
• Burn the DVD and/or create the ISO file is a plus, but not mandatory to me;
• Free and Open Source is a plus also;

Answer 1

I finally found a good software to do these things in Ubuntu. It's DeVeDe

From what I could test until now, it is far away from the possibilities of ConvertXToDVD, but it's a very good option to make DVDs in Ubuntu.

Requirements that match (from my tests until now):

• Convert various video formats (.avi,.mp4...) to a format that's readable on a DVD player;
• Add subtitles and change the text format (font,color,screen position) for them;
• Create menus with custom options and background sound;
• Free and Open Source;
