i am not sure if that is the real XCIPTV app from the official website:

However, smart tv's having limited cache/memory and possibilities of apps. better try IPTV SMARTERS or SMART ONE iptv app. but you would need to reduce bouquet list in order to reduce m3u file size...
@snubbet the best would be to talk to your reseller. He is the only one who has access to your dashboard and that might be helpful to guide you and find a solution.
looks like samsung smart tv has limited cache/memory and missing codec for the vod movies/series.
try another iptv app, with a little of luck you might get the right codec installed.
the support within this community is dedicated to rapid iptv, you won't get support for other "cheap" providers here...
better get in touch with your reseller, he is the only one who might be able to help you with above case :(
Channel editor and bouquet list are two different things.
The channel editor has some bags and is beta, not 100% working yet.
That's why most people just using the bouquet list.
