The live TV stream is sourced from a Hauppauge QuadHD tuner. When watching live TV you can literally open the OSD and see that the gray bar is being shortened as the green bar advances. This is confirmed in practice as well because you can hit back 10 times in a row and it will only go back by maybe 10 seconds and no more--then it forces you to play. I believe only the Xbox One app has this issue and it's across many accounts.
Considering how WinTV works (accumulating gigabyte files), there has to be a whole lot more data than that sitting on the server but the Xbox One app refuses to acknowledge it exists.
Version of the Xbox One app is 1.1.272.70
Version of Emby Server is 188.8.131.52 beta
