"Best" is subjective. If you are a Hollywood studio authoring a new movie, you would be using Scenarist to incorporate all the features that are supported by the technology such as BD-J Advanced Interactivity.
The average video production company would not be best off using Scenarist, as it would be extremely expensive to purchase, make the authoring process take MUCH longer, and possibly require a specialist to use the program.
The other option is to use DVD Studio Pro or Adobe Encore for authoring, as it streamlines the authoring process yet still allows for a decent amount of control and integration with other necessary programs (such as Adobe Photoshop).
Unfortunately DVD Studio Pro does not currently support BD Authoring, so your options are to use Adobe Encore, or a more user friendly (and less control) alternative such as Ulead, Roxio, or Cyberlink products.
I actually prefer using Encore over DVD Studio Pro, and recommend it for use with our
Pro Motion Menu Kits, which use advanced motion menus for Blu-ray and DVD. Many people have been turned off from Encore because of the many bugs it has. Luckily we have discovered the cause and found a solution for each and every one we encountered, allowing us to successfully author a Blu-ray disc which incorporates completely custom motion menus, seamless menu transitions, Scene Selection Menus with animated video of the chapters, Pop-up Menus, and wonderful H.264 compression.
I provide complete walkthrough tutorials on our website which demonstrates how to author a Blu-ray / DVD disc in Encore, and avoiding the many bugs of the program. This is available for everyone, not just customers. It can be accessed from the tutorial section of our website, under product tutorials.
