Man, I don't see it has options for recording or downloading video streams. Software that you have mentioned has all that plus some more functions what most of people here look for. Here it is not discussion about GUI, here it is discussion about recording
I have look at the complete product list of Mediavatar and as I can see, they don't have that kind of software at all. Considering download from youtube, there are tons of software that can do that, it is nothing special... However, thanks for your suggestions !
