Here's an interesting bit of this article- please get Channels working on newer Rokus if possible. Silicon Dust sure seems to not care (about Roku or Apple TV!)
Every year, I’ve asked HDHomeRun about potential support for Roku players, and every year, the answer has become more encouraging. In 2017, the company said a Roku app was unlikely to happen due to Roku’s refusal to license MPEG-2, which HDHomeRun uses to stream at full broadcast quality. Last year, Head pointed out that the MPEG-2 patents had expired, perhaps paving the way for Roku support in the future.
As of last fall, all Roku players running OS 9 support MPEG-2, which Head says is a precursor to a proper Roku app. Still, he’s not committing to any time frame, and SiliconDust clearly has a lot on its plate already. When I asked a follow-up question via email, Head seemed a little less certain than he did during CES.
“We continue to investigate a native Roku app and will work through any limitations to ensure an HDHomeRun-approved experience with minimal channel change or AV issues,” he said.
In the meantime, there is a workaround: Using the Roku Media Player app, you can select “All,” and then choose “HDHomeRun DMS” from the media device list. You can then tune to any live channel through the “Channels” folder. It’s not pretty, and there’s no guide data, but it’s supposed to work. (That said, I’ve tried this at home with both an HDHomeRun Extend and HDHomeRun Connect, and have only gotten video with no audio.)
