I have set up a system with an HDHomeRun tuner, a Chromebox as the main Kodi box in my media room, and a RPi3 as a secondary Kodi box in my kitchen (both running OpenElec 17 beta). The HDHomeRun tuner, Chromebox and RPi3 are all connected with a Gigabit switch, on an otherwise mostly unused home network.The Chromebox has a small 32G USB3 stick I use to store recorded programs (yes, too small for real use, but I'm still testing, and 32G is enough to record a few programs). The Chromebox is acting as the tvheadend server, and the RPi3 is using the tvheadend client (so are a couple of Windows PC I'm testing with)

I can watch TV just fine both from the Chromebox and RPi3, including HD programs. I can watch TV from any of my Windows PCs running Kodi for Windows, too. When I record an HD program, I can watch it without problems from the Chromebox. But if I try to watch it remotely (RPi3 or a Windows PC), the video is choppy and the audio starts choppy, then disappear. I can watch SD programs without problems

What am I doing wrong? Clearly the network is fast enough to watch a stream directly from the HDHomeRun. But once that same stream is recorded, it looks as if the network (or the Chromebox) is too slow to handle the stream... how can I start troubleshooting the problem?

Are you in the US?

Have you bought the £2.40 MPEG2 codec licence and installed it correctly on your Pi 3? The Pi 2 and Pi 3 can software decode SD MPEG2 (The Pi 1 and Zero can't) but you really need the licence for 1080i or 720p HD stuff, particularly HD 1080i as deinterlacing and software decode is too much for even a Pi 3.
