Live broadcast video falls behind after about 1.5 hours, with the audio remaining current. This happens on Apple TV 4K and tested on both of my devices. Also tested on iPad. Verified current audio by tuning in the same channel on my iPhone 16 Pro with iOS 26.4 and listening to both the iPhone and Apple TV 4K simultaneously. There is naturally a slight difference in delivery to the devices which is normal. The longer the Channels DVR App is left in the condition, the farther the video falls behind. Simply exiting the live broadcast and returning to it brings things back to normal.
Current setup:
- Synology DS220+ running the Channels DVR package. Software 2026.02.09.1530
- Source Tuners are 2 HDHomeRun Flex 4k. Firmware Version 20260326
- Apple TV 4Ks on tvOS 26.4 connected to network via MoCA adapter. All devices are connected to the same 2.5 gbps switch.
- iPad running iPad OS 26.4 connected via WiFi Unifi AP
This issue started within the last month or so when my wife pointed it out watching the Today show on NBC. Tested on other channels with the same effect.
