Is there a way to watch Nova episides? Also looking for Birding Adbventures. We're new to Roku, need help.
Keep in mind that Roku is simply a device that allows you to watch content from channels. Think of it as an extension for your TV. It allows you to pick certain channels via the Internet rather than over the air or over cable.
Nova has episodes available via Hulu+
-- which is a subscription service. It's $8/month for the Hulu+ catalog. Keep in mind that the Hulu catalog (free, watchable via your browser only) is not the same catalog as the Hulu+ catalog. If you look at Hulu's Website, and you see the little green "+" next to the show, it's available with a Hulu+ subscription, and, with a subscription, you can watch it on your Roku. If there is no little green "+" then you can't watch it on your Roku.
Some episodes of Nova are also available via Netflix
streaming -- also a subscription service ($8/month). If you go to the Netflix Website, the streaming content will be marked as such. Some content is disk only (not included with a streaming subscription), some content is streaming only, some content is both.
If you are an Amazon
Prime member, many episodes of Nova are available for free streaming via the free Amazon app you can find in the Roku Channel Store. If you are not an Amazon Prime member, you can purchase episodes for $1.99 each, or around $1/episode if you buy a full season. Again, you'd need to add the free Amazon app.
I haven't found any Nova episodes via a non-subscription service, such as Crackle.
By the way, these subscriptions aren't payments to Roku; they are payments to the individual service providers.
With cable, if you want a subscription service (HBO, Showtime, etc), you pay the cable company and they pay the service. With Roku, if you want a subscription service (Netflix, Hulu+, etc) you pay the service directly, not through Roku.
