One might wonder what Infuse is for and whether it is appropriate to pay for an audio/video content distribution application when there is an excellent and free one that I will not mention.
And yet...yes! Because in addition to a very beautiful Mac-style interface as we like them, Infuse is particularly formidable and effective if, like me, you have a NAS where a certain number of 4K video files and others are stored.
And if you add it to your Apple TV, you get the ultimate streaming solution, and much better than the free tool mentioned above.
Tried and approved!
