Generally, everything is normal, through an extreme beta was downloaded
By the way, it isn't sure, but can on 4.8.6 was the cause of failure downloaded by prior version (any of 4.5... in my opinion) the same roller, but without sound? I don't know; but now I deleted it after that the 1080p roller with a sound was safely downloaded
I seldom watch video, but this roller really hooked therefore decided to update the program. Thank you that it turned out!
There was a question with a choice of a place of saving on a external sdcard.
(though it not a problem - it is possible to transfer the file and manually.)
