Does anyone know why it is difficult to find old seasons of flyfishing shows on DVD? I'm referring to previous seasons of shows such as Flyfishing the World, Familiar Waters, Walker's Cay Chronicles, etc.

Considering that DVDs by Confluence Films (Rise) and the Angling Exploration Group (Trout Bum Diaries) are increasing in number, it would seem to be relatively easy and inexpensive to make old flyfishing TV shows available on DVD for purchase.

Perhaps they are out there but I'm looking in the wrong place?
