Perhaps the next advertisement is copyrighted and the copyright holder 
didn't want any unlicensed potential customers to see the ad.  :)

Kind of like the trailer for the movie Serenity ( 
http://www.serenitymovie.com/ ).  The High-Def version of the trailer ( 
http://www.serenitymovie.com/media/serenityT1_720p_8mbit_LTR_NR.zip @ 
131MB ) is actually encrypted WMV using Microsoft DRM!  (And, therefore, 
the trailer is only playable on Windows.)  Now, isn't the whole point of 
a trailer to give the movie broad exposure to a wide audience to try to 
increase the number of people who pay to go see the movie?

I guess you have to show your MS Windows CoA at the ticket counter when 
you go to see Serenity...  Either that or Universal knows that any Linux 
user is likely to already have the "browncoat" mentality (i.e. are 
"galactic outcasts"), and therefore is already planning to see the 
movie.  :)

OK.  Back on subject...  Have you tried running the videos through any 
tools to verify the streams?  For example, you could do some quick 
checks with tcprobe, tcscan, etc. (others?)
