Samsung TV DLNA Protocoll issue

Hello,

I am carrying out several tests with HA to send video streams to Samsung and Phillips TVs. With Phillips TVs, the tests were satisfactory, managing to select a media file hosted on the HA itself and send it for playback on the TV via the DLNA protocol, however with Samsung TVs from 2021 and 2022 (AU8000 and BU8000), the process does not work. Thanks if anyone has any tips.

Thanks.
