I'm able to play DVB-C channels as well as recorded videos from Panasonic TV on my Windows PC using vlc:
"C:\Program Files\VideoLAN\VLC\vlc.exe" "http://192.168.1.116:7501/VIDEO-H881241d44d46f8744154b38245775b0beb9ee063b0ff6b2e02f7acad79ebf487-a604d1773270748281091d05e88ebcca00000095"

but mpv does not open when launching:
"C:\Program Files\mpv\mpv.exe" "http://192.168.1.116:7501/VIDEO-H881241d44d46f8744154b38245775b0beb9ee063b0ff6b2e02f7acad79ebf487-a604d1773270748281091d05e88ebcca00000095"

Output for above is nothing, no vlc is starting.

We cannot help you without logs/sample.

What sample would be valuable for you?
The only way to reproduce this issue is to have Panasonic TV with whatever source of TV channels (like DVB-C) but I don't mind to send you "sample" Panasonic TV set.
I will try learn how to grab log file when trying to view recorded video by launching:
"C:\Program Files\mpv\mpv.exe" "http://192.168.1.116:7501/VIDEO-H881241d44d46f8744154b38245775b0beb9ee063b0ff6b2e02f7acad79ebf487-a604d1773270748281091d05e88ebcca00000095"
If I will succeed then I will attach this log file here.

run mpv.com -v http://192.168.1.116:7501/VIDEO-H881241d44d46f8744154b38245775b0beb9ee063b0ff6b2e02f7acad79ebf487-a604d1773270748281091d05e88ebcca00000095 and see what it tells you in log. There may be multiple reason why it fails to open a file.

By sample I mean sample file probably you could save it with curl http://192.168.1.116:7501/VIDEO-H881241d44d46f8744154b38245775b0beb9ee063b0ff6b2e02f7acad79ebf487-a604d1773270748281091d05e88ebcca00000095 --output vid.ts ctrl+c after few seconds to get short file. And see if it works in mpv, if it doesn't share this file.

[ffmpeg] http: HTTP error 406 Not Acceptable

Something in ffmpeg http requests doesn't work with media server on your tv.

--http-header-fields='Accept: */*' --user-agent='curl/8.12.1' or something like that, maybe it will work better.

So it looks like it try few times to open a stream but it also fail with HTTP Error 406 but eventually at the end is able to start playing video:

qt debug: on_player_state_changed VLC_PLAYER_STATE_STARTED
oldhttp debug: HTTP answer code 200
oldhttp debug: Server: Panasonic MIL-SV/1.0
oldhttp debug: Content-Type: video/vnd.dlna.mpeg-tts
main debug: using access module "oldhttp"

To me it looks like mpv is unable to use "oldhttp" whatever it means.

Unfortunately the same error:

[ffmpeg] http: HTTP error 406 Not Acceptable

OK, so mpv can't play Panasonic tv streams, but vlc can.
What a pity.

DVB-C stream #16438

Uh oh!
