Image Quality versus Image Delivery

DVDs and Blu-rays are most frequently evaluated in terms of image quality, that is, the resolution and density of the digital image. the higher the resolution, the better the image.  The importance of the delivery system is less often commented on, but deserves attention since screen sizes, projectors, and kinds of screens all make a huge difference.  To give one example, I have been watching DVDs on a 52" LCD with a Sony Blu-ray player that I had seen before on a 32" cathode ray TV set.  I generally feel like I am watching a new film.  I can see all kinds of things I missed the previous viewings.  One thing I appreciate about the reviews at is that the reviewers list the specs of the equipment they use to watch the DVDs and Blu-rays they review.  I hope that info becomes standard practice for reviewers.
