Help and support for HDHomeRun DVR and HDHomeRun software for Windows 10, Mac, Android, XBox, etc.
I believe the current status is that an update went out in the past two weeks which included the MPEG2 decoding fix. (I received this on both of my 4K sticks.) However, EU (especially UK) users may have some more waiting, as apparently there is still a problem that affects H.264 interlaced streams, which are quite common over there.
Live TV is still not fully working on DirecTV Now. They replaced my sticks and the problem persisted. I realized it was due to my Audio setting set to Stereo, it causes some channels to freeze. If I changed the audio to any other option, the voices and mouths were off but it never freezes on any channel. Put it back to Stereo to correct the lip sync and it freezes on some channels. So weird that it's the Audio setting on 4k stick.
