Using Beta version v2022.07.07.2314 on all clients. When I disable the HLS option, I don't seem to have any problem playing the recordings. I did notice a little jitter in one of the videos that would consistently cause the player to lockup only when using the HLS option.
While using the HLS option, I simultaneously steamed 5 different channels on five clients. At the same time, I started a browser transcoded live stream. Then I started recording 2 other channels, utilizing all 8 of my tuners. Everything seemed to work very well.
My server is only a Beelink U59 running Windows 11 pro. My storage is a 4TB Westen Digital USB3 portable drive, that I know many of you think is somewhat lame. It seems the Channels server software is very efficient. I know Apple TV is the preferred client, but your support of Android and FireTV is greatly appreciated.
