It's perfect for things that just need a modest amount of bandwidth, like a TV. Most streams are a few tens of megabits, and that's about all you can reasonably expect from powerline networking. When you try to use as much bandwidth as you can, they fail in sometimes spectacular ways. I have some old Radio Shack 10 Mbps ones that have brought a high end Juniper to its knees when the Radio Shack box's "collision" LED was fully lit. Newer devices do better, but it's best to just use powerline networking for things that need steady, continuous traffic.
