And 'possible to disable the right mouse button in a Flash movie?

Yes, you can add:

<PARAM NAME=menu VALUE=false>

and "menu = false" to the attributes of <EMBED>

As the following example:

<OBJECT classid = "clsid: D27CDB6E-AE6D-11cf-96B8-444553540000" codebase = "http://download.macromedia.com/pub/shockwave/cabs/flash/
# version = 5,0,0,0 swflash.cab "WIDTH = 640 HEIGHT = 480>
<PARAM NAME=movie VALUE="filmato.swf">
<PARAM NAME=quality VALUE=high>
<PARAM NAME=bgcolor VALUE=#FFFFFF>
<PARAM NAME=menu VALUE=false>
<EMBED src = "filmato.swf" quality = high bgcolor = # FFFFFF menu = false
WIDTH = 640 HEIGHT = 480 TYPE = "application / x-shockwave-flash" pluginspage = "http://www.macromedia.com/shockwave/download/index.cgi?
P1_Prod_Version ShockwaveFlash = ">
</ EMBED> </ OBJECT>
