The real issue with 40 inch displays is the preferred viewing distance. If you are willing to sit five feet from the screen, you will see the difference between 480P and 720P - by the way Doug you would NOT see any improvement with Blu-Ray on a 40 inch screen at five feet, unless you are looking at one of their demo discs where the purposely blur the SD-DVD content. The problem is that the vast majority of consumers will not sit five feet from a 40 inch display - 7-10 feet is typical. 



I sit 8 feet from my 40 inch TV, and there is a huge difference between
real 720p and 480p converted to 720p. There is no difference
between the best 720p and the best 1080i, as this is a 720p set.



Why use a de-interlacing display. Get a DVD player with progressive output.


Well, interestingly, my 720p TV set does a better job of conversion that
either of the 480p DVD players I have/

Craig, you are just wrong about the necessary viewing distance
to see differences. Its a good 50% greater than what you say
(i.e. its actually 7 or 8 feet when you say 5 feet.)
