Only can watch HLS stream when I stream it from VLC

I am trying to watch the following HLS stream on my old Sony Bravia TV from 2010: https://pbs.lls.cdn.pbs.org/est/index.m3u8. If I put it directly in Serviio, I just get an error message on my TV. However, if I put it in VLC first, and then stream it to Serviio over an HTTP stream with MPEG-TS transcoding, it works just fine. I have tested this multiple times, so it is not just a coincidence. What is different about the VLC stream that makes it work on my TV?

The Serviio log is attached. It shows me adding the stream to my Serviio online sources, loading the stream successfully in VLC on my PC, and then unsuccessfully loading the stream on my Sony Bravia TV.

Today, I found a contradiction to the "Stream with VLC to get it to play" rule. Here is the ffmpeg -i output for the stream that won't play, even after I run it through VLC:

Update: I realized that I forgot to enable MPEG-TS transcoding. That's why it wouldn't work. This post can be ignored or deleted.
