I got fed up with arguing with YouFail / Goofle video - as I used royalty free music on some of my vids, yet they still stated it was copyrighted material.
Then they plastered my videos with adverts over the top, which hid my own lower 1/3 text ruining the detail.
For me, that was the final straw and I looked around - with Vimeo winning it in the end. Vimeo has been good ( bar an issue in January about an incorrect payment being taken from my credit card )
