i've got a few .swf movies that load into a main one via a menu. they all load fine no prob with 100% preloaders and all but when run locally they are smooth and on the net they drop frames seriously and appear all choppy as a result.
original .mov are fine, all 25pfs pal and import was to a flash movie also of 25fps with no sync to flash frame rate. exported at a high enough quality to be fine and the host movie is also 25fps.

any ideas why im getting this problem folks?

Cheers
