Modern alternatives like DVD Styler (open source) or ConvertXtoDVD are free/cheap and legally portable.

In the world of digital video, few names command as much respect as TMPGEnc. For nearly two decades, Pegasys Inc. has provided industry-leading tools for encoding, editing, and authoring DVDs. Among their most beloved legacy products is TMPGEnc Encoder Works 4.0.9.37 —a version that many professionals and hobbyists still consider the "gold standard" for creating complex DVD structures with high-quality menus.

However, with great power comes great responsibility. Respect the intellectual property of Pegasys Inc., support developers when you can, and use portables ethically.
