I noticed this issue on my Hisense Google 4K TV. When viewing the channel on Channel DVR, the recording and the live feed plays jerky. When watching the same channel on the HD Homerun app, it plays smooth with no issues. To rule out the OTA HD Homerun Prime, I tested 2 other TV's and my phone (Tivo Stream 4K, Apple TV & iPhone 14 Pro), it plays fine. Just to point out, it's not on all OTA Channels, just the ones running HEVC.
Any ideas of how I can get the recordings and live stream to play right on the Hisense Google TV? I have done both, moved the Channels DVR app onto a Thumb Drive as well as playing it on the internal storage and got the same problem both ways.
