Sure, and nobody will get tired of that entertainment, start looking for some other kind? Write their own books? use the spare cameras for a little film shooting. Hey with all teh computer skills they are deveoping they might just animate them. Or maybe go old school with recreaational pursuits in a limited environment. Kinda sucks when the population grows ahead of schedule though. How do you estimate how many condoms will be needed for a 50 year flight? Of course they expire in 7 years anyways, so after that... no, i'm sure a few old videos will completely prevent cultural divergence.
