[CentOS] Apple movie trailers on Centos6/Firefox

Hi all!

Once again, Apple has messed with their trailers/website such that I can
no longer play their trailers on Centos 6 (note that it still works
fine on my two Fedora machines, F17 and F19, without any special
settings.

on Centos, I've long ago found that by setting the user agent to certain
values I could make it work, but now that no longer helps. when I try
to view a trailer all I get is a "download Quicktime" page.

When I was running C5, I used mplayer plugin to do the video and it
worked fine. after installing C6, I discovered that Totem also worked
without the need to mess with mplayer installation. then all of a
sudden, a couple weeks ago, it stopped working.

at the same time, the choices they offered changed, so now they only offer
"automatic", "480p" or "720p".

this link is to one I can still play: http://trailers.apple.com/trailers/independent/elemental/

and this is a newer one I cannot: http://trailers.apple.com/trailers/disney/monstersuniversity/

I am (and have been) using the User Agent Switcher plugin for firefox
(for several years) to make this all work, and until recently it has.
Using that plugin, I find either of these settings has worked:

useragent description="Quicktime 7.6.2" 
useragent="QuickTime/7.6.2 (qtver=7.6.2;os=Windows NT 5.1 Service Pack 3)"
appcodename="Mozilla" 
appname="Netscape" appversion="5.0 (X11)" 
platform="Linux x86_64" 
vendor="" 
vendorsub=""

or:

useragent description="Google chrome" 
useragent="Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/535.19 (KHTML,like Gecko) Chrome/18.0.1025.168 Safari/535.19" 
appcodename="Mozilla" 
appname="Netscape" appversion="5.0 (X11)" 
platform="Linux x86_64" 
vendor="" 
vendorsub=""

I'd appreciate hints on how to once again do a end-run around Apple's
attempts to fence me out.

Thanks!
