Make sure to add the https link of your logo and you do not have to add any tag like [kenplayer][/kenplayer], you just can add the embed code that you can find under every video and copy and paste it anywhere you want your video to appear.
If you load videos using the Ken Importer Pro plugin, it will automatically grab the code from the XVideos and other sites and add it and the KenPlayer will automatically add its own player so you do not have to do all the work.
The videos could appear twice, because you have inserted the code in the description. You should just add it once.
