AotC - DVD vs Blu-Ray Preview:

The DVD capture is one frame off, but Yoda's head doesn't turn as much as it does in this Blu-Ray Preview. Yoda's looking at Dooku now, doesn't quite get there in the DVD version. So might be a new head. *EDIT* or an extended shot, Dooku's cape isn't matching... Looking at it a little more, the extended idea makes sense, there's no noticable music or dialog just sound effects and if you watch the cloak, the wrinkles sweep in and out. Guessing an additional 4-6 frames, maybe more.

*EDIT*

this change and others? would explain why the FSK reclassified AotC according to reports: http://originaltrilogy.com/forum/topic.cfm/Star-Wars-coming-to-Blu-Ray-UPDATE-May-4th-2011/post/514625/#TopicPost514625
