I'm using Windows 7 Home Premium version of Movie Maker.  I saved my completed movie with High Definition Display, which is essentially the same as the recommended save setting.  I then burned it on my DVD.  However, when I played the DVD in my blu-ray player, it does fill the whole  TV screen but it looks digitized and definitely not high definition.  I've even tried the "burn a DVD" setting, which is only 480p.  It's not clear, but looks slightly better than the high definition setting!  My digital photos are excellent when viewed directly from the camera, so I'm very frustrated that I can't get the same good results when burned to a DVD.  Any suggestions?  Thank you.
