Can't play any m3u IPTV channels

[harry]

Hello Guys,

I am trying to play a publicly available stream which works in both VLC and WMP.
https://clb.cdn.bg/bnt1/fls/bntW.stream/...020b4b3c58 (http://tv.bnt.bg/bntworld/)

I added the channel and the SOURCE URL, but when I try to play it in nPVR I get no video playback at all.
I only see "Please wait" for a fraction of the second and then nothing. There is nothing in the logs as well (all logs are attached).

Is this M3U stream (video codec is H264) supported?

If you try scheduling a recording on that channel, can you play the recording?

Hello Sub,
Thanks for taking a look.

I don't get anything recorded and I see an HTTP Error 500 in the logs:

I did a quick Wireshark capture of the HTTP request sent by the nPVR recorder and the working VLC player and that shows that nPVR doesn't send an "User-agent"
header and without user-agent the server responds with 500. In this particular case any value of the User-agent header will do it but it can't be missing.

Is there a way in nPVR to specify an user-agent header i.e. "User-agent: nPVR"?
If not, that would be an useful enhancement since some streams require a certain "user-agent" header.
