Tvheadend

Currently, I have two tvh setups, one act as "server" and one act as "client". On the server side, it is serving mpeg2 ts ATSC streams via pcie tuner.

I am trying to export the playlist from the tvh server and import it to my tvh client via automatic iptv network.

The issue is if I just add the playlist, tvh would not be able to find any services/pid. If I use a/v library or pipe, it would be able to find the services. The links play fine in video players such as potplayer, vlc on windows and wget works with those links as well.

This is what the log shows when I try to scan the muxes without a/v library or pipe.

I have done this kind of tvh->tvh setup before and it worked, not sure what is causing this.

Any ideas on what may be the issue?

Thanks.
