XeMoviePlayer is a video player to be used in the Adobe Air environment, with which you can view the files in FLV formats (therefore, all YouTube videos). That was the initial objective, but it turns out that it is also operational with other formats such as MP4, M4V, MOV and 3GP.
It is a very effective program although something basic. To play YouTube videos on XeMoviePlayer, just copy and paste the video address in the program, being equipped with all the usual options of any media player, and also having the ability to view and save images of the videos in format JPEG
You can free download XeMovieplayer 32, 64 bit and safe install the latest trial or new full version for Windows 10 from the official site.
