I've been trying to watch some old episodes of Nova on my iPad, but the Nova website only seems to stream the episodes using a Flash player. I think several seasons are available on iTunes, but paying $3.99 per episode for a free PBS show seems a little too expensive. I've also noticed the show is available on Hulu, but they only seem to provide the last couple of seasons.. The episode I'd like to watch is Secrets of the Samurai Sword from 2007, which is available on the PBS website but the iPad app only offers more recent episodes. Any help would be much appreciated!
YouTube is your friend, in this case - you can watch for free..
Use the built-in YouTube app and run a search for
Nova Secrets of the Samurai Sword. While I don't have an iPad to try this on, I was able to bring up several instances of that particular video on my iPhone - I imagine that this method would also work on an iPad.
Here's one of the links if you'd like to check it out from a computer: http://www.youtube.com/watch?v=uMLG7FvDuCI
Update (Nov. 2016): Since full Nova videos are no longer available on YouTube, the only other option I've found is to go to PBS directly:
However, to actually view the videos may require a membership/passport to your local PBS station (mine is KQED).
