So this is normal why the speed of moving pages in the video section is so slow.
There is one cause … “TV Shows” using the “Get Content Info” feature
When “Get Content Info” for Movies & TV Shows it downloads and creates a *.metathumb which are in fact *.jpgs (rename the extension to see)
Movies metathumbs are " Small" eg. 154(w) x 231(h) around 10kb
TV Shows metathumbs on the other hand, are " Huge" eg. 680(w) x 1000(h) around a whopping 500kb! …
which causes massive slowdown to point where it’s pretty much un-usable.
solution: batchrename TV Show metathumbs to *.jpg and batch resize them
(personally, i use 300x450 under 70kb which is a compromise between picture quality and speed. other peoplel use 200x300 which is fine as well 
)
For batch renaming and image resizing, i recommend these 2 *Free* easy to use softwares.

Trivia: The old WDTV Gen1’s it was recommended to use 120x180 any bigger, then navigation slowed down.
EDIT: also … another cause of navigation slowdown is if you Manually set the Video Output to 1080p 24hz… sure 23.976fps video is smooth as silk with this setting … but it also causes UI slowdown (notice the home menu scrolling is not smooth after setting this setting)
