Image Quality Loss and Desaturation in Flash

I have noticed a significant loss in JPG quality in published flash files.
Even with jpeg quality at 100 and the swf uncompressed I have noticed,
in particular, significant desaturation in both images contained in the library
and those loaded dynamically by the actionscript/xml.

Does anyone have a clue about this?

I have searched the forums to no avail, and I can not figure it out.
Is this an accepted problem in flash mx?
Anybody? Any thing?
