I have both youtube premium and ytd downloader pro and ultimate on 2 computers, an acer with 2.7 Ghz cpu with full hd and a 4k asus with 2.4 Ghz cpu, certainly enough to get the job done if it is possible, but I stll get corrupt videos if I can download them at all. I have an ac network adapter on the acer and an ax on the asus. I have tried both broadband router hotspots and cellphone hotspots.
