ZuneBoards.com recently released ZuneTV, which is a web site for downloading video files. It operates much like YouTube.com, except it allows you to also download videos in Zune compatible format. So far as I can tell, the video downloads are free (you need to have a ZuneBoards account to download files).
The nicest thing about this site, is that you won’t need to use external programs (such as Orbit Downloader) to download the files and convert them. The limiting factor for me, is that the video content seems lacking (having similar user-generated videos as YouTube.com). I’d rather download TV episodes, documentaries, etc. than Charlie the Horse in Candyland.
So for now, I’m still sticking with hulu.com and veoh.com for TV Show downloads. And, I’ve got my TV Tuner card with Vista Media Center recording and converting scheduled TV shows for my Zune!
