Our favourite DVD and Blu-ray writing software which has now reached version 5. Encore can do nearly everything you want on a DVD and Blu-ray disc including subtitles, different audio tracks and slideshows.
Encore integrates exceptionally well with Adobe Premiere and Adobe After Effects through the dynamic link - which saves huge amounts of time when authoring DVDs.
Available either in a bundle with Adobe Premiere Pro CS5 or the Adobe Production Studio.
A DVC-made tutorial on using Encore is also available here.
