memory is for aps only
Sorta what I do with roku 4 and its usb. Plug in a laptop HDD and you can load 500 to 1000 full lenght movies to view with a Roku 4 now the micro SD card is only 32g and holds only aps but 32g will hold a few cartoons not movies even in low or junk defintion you may only get one movie but the resuluton would be so poor it would not be worth watching. Best to get a USB laptop HDD and case Laptop HDD get up to 4TB and thats 2000 movies. Good for a trip to Mars and back.
A:AnswerWe had a similar issue on a TV with the Fire Stick and a soundbar. I had to go into the TV Setup menu and start enabling inputs and devices to work. Can't remember what ones but there weren't to many options. Try looking in there.
