@Francis-Auger, disabling Transcode interlaced live tv sort of helps but brings its own issues and bugs. With that setting, more than half of my channels’ audio is out of sync to the point I can’t watch. Like at least a second or more. I started a new thread a few days ago for that bug but haven’t heard a response. There also seems to be an issue when trying to tune a channel, sometimes it will just hang until you select a different channel and then go back to the original channel.
