Here's a problem with playing back DVD's: they don't have upconversion in the and/or like you have console
Blu-ray players and newer DVD players connected to the appropriate display using the HDMI connection. As such, it doesn't try to "upscale" the resolution to take advantage of the sharpness available with 20" or later widescreen monitors that have HDCP, and even on a well-mastered DVD like the Extended Editions of the
Lord of the Rings movies you can see the very distinct "fuzziness" in the background details. Meanwhile in the setup I mentioned originally, when you play back a real
Blu-ray disc you get the full resolution of the disc, and on a movie like Disney/Pixar's
Cars (my "reference" disc to demonstrate the amazing sharpness of
Blu-ray format) looks totally amazing even on a 20" widescreen computer monitor.
As for Apple not supporting
Blu-ray, up until very recently getting a license for the technology was a complicated, expensive process. But now that you can get a simplified, "single-point" license for this technology, it also means dramatically lower licensing costs, and that could point the way for Apple to support
Blu-ray technology on the iMac, Pro and higher-end .
