I downloaded some video's from YouTube with Free YouTube download from DVDVideoSoft. I downloaded it as avi files. On my computer I can watch them with VLC player. With Nero I burned them on a dvd which I can watch on my TV. When I put these avi files on my Essential, I see them in my file manager, but when I select them to watch, it doesn't play. Is this due to the "youtube rights"? Or is there another problem? All my other movies, avi, iso etc are showing great.
