CDL 2005-2006 Framerate?

[chocopockymaster]

My memory of the end of 2005/beginning of 2006 isn't very clear--CDL 05-06 seems to me like it was filmed at a higher frame rate than Ayu's other concerts, and if memory serves its the only one of her concert releases that has that "smooth" quality to it. Is the frame rate actually higher? If so, was the reason for that ever discussed in like, liner notes or something? I'm watching it right now and the difference is so jarring, lol.
