The problem is very visible in sideways panning shots or on moving objects, which gets a choppy movements occuring every 5-6 sec. The exact same video files plays back fluently on a WDTV box. Tested with 720p and different lower resolution files. Also tried different output settings on ATV2, 720p 50hz or 60hz and 480p, but no luck.
A discussion on the XBMC forum suggests disabling any motion improvement features in the TV, but i don't see any option for disableing the BV10s "Motion Picture Improvement" feature...
Any thoughts or suggestions would be greatly appreciated.
(PS. I have the same behavior when playing movies from my MacBook Pro via a mini displayport to hdmi adapter on the BV10.)
