You may want to try going through an online video specialist. Does Amazon.com do hard-to-find videos? Also look for Barnes & Noble and/or Borders online. They may be able to do a rare search for you. I know they do rare book searches, they may also do a rare video search. You may get lucky and they'll have one stashed in one of their warehouses.
I found a copy of Samuel Barber's "Vanessa" after searching for 2 years. Now I occassionaly see them on a shelf. It's frustrating.
oh! If you find a copy of Menotti's "The Medium", please let me know. I'd love to get my hands on one. CD or video would be great.
