Youtube is horrendously slow on my Roku 2; fortunately, I have alternatives on my setup.
By the way, another channel we added recently is Spuul. It has a nice selection of Bollywood movies, including many which are free (and commercial-free), though the best ones require payment or a subscription.
I looked into Sling. Interesting but not sure I am ready to fork over more for more paid content. It’s good to know we can access the cable content if we want though.
