If its H264 Interlaced content only you are watching that is Transcoded from a HDHomerun you will likely be fine.
Basically the Android OS looks like it refuses to hardware decode this mpeg2 Interlaced combo using mediacodec.
The FireTV's have issues, the Google Nexus HERE, the nVIDIA Shield is having problems HERE , and the new AML S905, if its using mediacodec will also have issues.
They all default to ff-mpeg2 Software decoding and deinterlacing, which is inferior to superior quality deinterlacing out of a hardware VPU (Visual Processing Unit).
For excellent quality mpeg2 TV broadcast hardware deinterlacing on a budget you grab a AMLogic Box, preferably a S812-H or a S905, and use amcodec to hardware decode.
If you want 1080p Netflix with a AMLogic box the only option is a WeTek Core, that can also run the remote control friendly Android TV OS version of Netflix with Android OS dynamic refresh rate switching, just recently being included into that.
Isn't there also a problem with interlaced MPEG2 in VOB (Programme Stream) vs TS (Transport Stream) formats on some platforms? ISTR that the nVidia shield was fine with interlaced MPEG2 in one format but not the other - and at one point they changed which one worked well ? (Wasn't this also the case with AMLogic platforms too?)
Does the Core now do high quality hardware deinterlacing and decoding of native interlace MPEG2 content in both formats (DVD and Live/Recorded TV) now?
