Now it has become very difficult to download HD videos from Youtube. KeepVid and SaveFrom - Youtube is probably blocking HD videos download from most popular channels.
I've personally come across this problem over a few instances where I was not able to downloads videos mainly HD videos from popular Youtube Channels (mainly brands).
Just wanted to inform you guys and should anybody of you have any solution to this problem like any other alternative for downlaoding HD videos from Youtube, do let me know in the comment section.
