import movie clip problems - pls help

[maydays]

I have 1 movie clip with some images (.JPG's) .... everything works fine, this movie clip is used as a navigation menu, there is 1 big .JPG wich is for background, and some small JPG's that appear on mouse over.... the problem is that when i copy all items from the above movie clip library to a another library, i loose quality on the small images, i really don't know why ... all images are jagged, properties are still the same (Photo JPG with Allow Smoothing ) ... i have also tried to import the .swf of that menu, but when i import it, in the library it does not appear like a movie clip, it appears like graphic .... any other .swf's imported are ok, but this one no .... i am really lost with this ...don't know what is the idea .....

if anybody knows anything, please let me know.

thanks.
