SS IPTV

I have uploaded the playlist on the SS IPTV site and on it i can see all the items (around 1000). But on Smart TV (Samsung F series) my playlists only shows first 306 items... On the playlist there are some live channels (.ts) and some movies (.mkv). The 306 that i can see are the first 306 items (all channels and some movies). VLC or KODI shows all items....

You cannot use "My playlist" section for movies and channels at the same time, "My playlist" is only for channels and "My videos" is only for movies. Separate movies and channel and write again if the problem still takes place.

First i also thought so but since some of my movies were shown on my playlist i thought problem was something else...
Do i just make a new m3u list with .mkv links in it? Will try later and post results... Thank you for the answer....

Yes, you need to make another playlist for *.mkv
The problem may be somewhere else, but this is thing must be fixed first of all.

OK, that solved the issue
Now i just have a problem with one stream (sound is ok but the picture is frozen). It works on VLC but not on SS IPTV....
