[Plant-education] Source for Private Life of Plants DVD

[Carmen]

Hi everyone,

I teach high school Biology and would like to use Attenborough's Private 
Life of Plants series with my classes.

Unfortunately, I have only found Region 2 versions of the DVD available for 
sale.  Does anyone know of a source for purchasing a Region 1 version of the 
series or a downloadable version I could show my students?
Thanks in advance for any assistance you can provide.

Sincerely,
Carmen Vanegas
