If you have a high definition TV this really isn't news for you, but for your friends and family who don't yet understand the difference this may be interesting. This guy took captures from Fellowship of the Ring, both on DVD and from a high definition broadcast to compare the two. On the first page is a mouseover comparison of the screens at DVD resolution, but if you click them, you can see the difference when the DVD is upscaled to match the high definition resolution.
There's a lot to be said for additional visual information, but in the end, do you think this provides a powerful argument for upgrading to HDTVs (and high definition DVD's) or is 480p just fine for you?
Thanks for the tip Tyler! [Also via digg]
