this application is a great idea and is surelly understimated.
I like youtube videos ...in fact did not know about google and yahoo videos until i saw at tvtube ...the problem is that was not nice to keep adding favorites in safari. Or sending emails with the links.
with this application i keep all my video links organized, from the various sources, and there is the possibility to send the file to someone else, with direct access to the videos.
nice.
