Thank you for the replies and I apologize for not being more clear. I am in the preliminary stages of setting this up and testing. I have not setup the epg or pvr yet because I am still learning and focusing on getting the stream correct. Anyway, I have a raspberry pi 3 (first version) loaded with tvheadend and it is wired directly into my netgear r9000 which is one of the fastest routers on the market. I have an iptv sub and a Hauppauge 950q tuner connected to the pi3.
I have 3 firetv's and one raspeberry pi as clients. The m3u files and the tv tuner loaded into tvheadend and the clients can see the channels. The raspberry pi3 has the mpeg license and plays the tv tuner clear without any problems, but the firetv products are producing a choppy, lagging slow and fast pace video. The clients are all wireless and are receiving 50 mbps download speed as per the speed test. My other wireless products that I have average around 300mbp so I believe the router is functioning correctly.
I have tried adjusting the settings within kodi as per many posts that I have read on the net and these issues still exist. I believe that the problem has something to do with the firetv or settings within kodi because there are no hiccups with the client raspberry pie or windows 10 kodi. It seems that the firetv is not compatible with streaming the mpeg2 video that comes from the turner. When I change the "render setting"s within kodi, the iptv acts up and buffers. Otherwise,the iptv video for the most part is good, but a little jerky.
I hope I have explained this fiasco a little better and I am game for any suggestions.
Thanks for the help
Lisa
