Zero experience with Apple. With the Roku box you have to add an applet, called a channel. Flickr is a channel but if you want to stream from your personal computer to your Roku and then the TV you have to add a private channel. It sounds complicated. It is really quite simple. There are several different providers. You only need one. Finding the one that "fits" you the best may take a little digging.
As I am in the process of building a new desktop, I would rather play now on the old hard drive that I am going to wipe. If I screw something up it won't haunt me for years.
