If you don't have HDTV channel, and don't watch lots of DVD, 16:9 is useless. basic cable looks urgle in HDTV set. And it may burn the TV for certain types. You need to keep a second regular TV for CNN.
HDTV + progressvie scan DVD is nice for movies. HDTV channels are crystal clear, but you need to pay moeny for the quanlity.
