Problem watching videos on TV topic

Hello.
So far I've never had difficulties watching videos (via Wi-Fi and using Samsung video player) on my Samsung TV. But I've reinstalled my (custom) Rom and since then my videos displayed on TV have jerky movements. Unfortunately I deleted the Samsung video player and now I have to use screen mirroring functionality that could be the problem. I tried reinstalling the Samsung video player (via different apks found on internet) but it failed.

So, could someone help me reinstall the Samsung video player on my note 3?

Thanks in advance!
