I'm aware of all of that. But some of us have routers that do, and to date, the Roku is the first device I've encountered that won't use them. I have had 3 or 4 different Android phones, an Android tablet, two Kindle Fire's, 3 laptops and a couple of HP printers that all worked just fine on the DFS channels.
My only real point is that it's a shame that the Roku will not. If I wanted to use it, I'd have to set my route to one of the few non DFS channels and share that bandwidth with my neighbors. Instead of having bandwidth of my own.
There is no guarantee you wouldnt encounter "sharing" or "non-interference" on a DFS channel - just the opposite, that being the nature of DFS:
1) Expect your Auto-assigned DFS channel assignment to change due to interference (with a period of disconnectivity for most clients), and
2) expect your Manual-assigned DFS channel to drop entirely (device offline).
3) Additionally, when automatically re-assigned, the new channel may or may not be a DFS channel.
4) Furthermore, there are a lot of false positives for the regular (required) interference checks on DFS channels, thus creating a lot of channel reassignment and disconnectivity.
So, ultimately, you may experience more connectivity problems using/enabling DFS than not/without.
You can then understand why a streaming device would avoid making connections in scenarios that anticipate increased/frequent periods of disconnectivity due to interference/channel reassignment.
