DVD quality isn't even close to HD. ...
Thanks for your
opinion. Certainly 480p isn't HD, duh. However 480 p image quality can compare quite favorably to a highly compressed 720p from a Sat or Cable provider. Also, renting a DVD disk from Netflix provides a 480p image, viewing an instant pick from Netflix likely provides no better then a 480p image - or an up-rezzed image which will not result in an improved image.
I have a Pioneer Elite Kuro plasma. Not
all movies are of better image quality on BD compared to DVD.
Additionally, if the Netflix source for an instant viewing item is a DVD, their up-rezzing it to 720p or 1080i for transmission to your STB will not result in an improved image when compared to having the DVD at home. There is, however, a big improvement wrt timeliness of delivery and having the ability to choose from numerous movies at the spur of the moment.
