I purchased a small 24" LG TV for my kitchen area specifically because I could utilize the Xfinity app for live TV. Everything on the TV seems to work via the network (actually have it plugged in to the ethernet directly). Netflix works, Amazon works, YouTube works, etc. The only thing that does not work is the Live TV in HD on the Xfinity App. It stutters and lags and never can actually run a show. Interestingly the Xfinity app plays SD channels and Recorded HD shows via the network just fine. Anyone else have this issue? Is this an issue with the TV or with Xfinity?
