Downloaded shows won't play on iPad away from home network

I downloaded about ten shows to watch on the plane on my iPad through the TiVo app. They all showed as downloaded, but when I tried to access them on the plane, I get an "Updated Video Required" message telling me to update by hitting the show's download button. When I hit the show's download button, it won't let me do this because I'm not on the home network. The show's were downloaded in their entirety last night. I watched each one download, so don't understand why it should require an additional download. I won't be home f six weeks so th is very frustrating. Does anyone know how I can fix this?
