TJ,
Most good videos are scripted, otherwise they come across as shoddy and unprofessional, imo. I think the Audio Advisor videos for BCD, BDP, B100, are quite tastefully done. Of course, one could add animations and "special effects" to enhance the presentation, but the essence of how these units operate (buttons, jacks, etc) is communicated adequately, imo. The thing is, there needs to be a balance between objective revelation of features and grandstanding salesmanship American-style. I think Bryston avoids the latter.
cheers
