HD DVD vs. Blu-ray: Which is Better?
“Which is better in terms of quality, Blu-ray or HD DVD? I’m quite confused by these 2 media types and would like to know which one is better in quality. Please help.”
Blu-ray and HD DVD are the two new competing formats designed as the next step in DVD technology to bring high-definition movie content to HDTVs. Unfortunately, the two formats don't play nicely together. No HD DVD player will be able to play Blu-ray movies and no Blu-ray player will be able to play HD DVD movies. If you really want to go high def, which format should you choose? We can't decide for you, but in this guide, we would like to show you their differences. Just check them below.
Outline
Part 1: Blu-ray vs. HD DVD: Which is better?
HD-DVD was designed to be cheaper and more convenient for upgraders from DVD, and many commentators compared them to VHS and Betamax to argue that cheaper and more convenient would win. But this time, the higher-quality format won the battle.
Both formats support identical audio and video codecs (compression systems), one of the two critical factors in quality. But Blu-ray wins handedly on the other: bit rate. Its physical disc format has 60% higher capacity than HD DVD (50GB/disc vs 30GB/disc), allowing higher bit rates and therefore better image quality. DVD, for comparison, fits 8.5GB/disc.
1080p HD has six times as many pixels as DVD-quality video, so all other things being equal needs six times the storage capacity (though advances in video compression reduced this by a bit). Blu-ray provided enough capacity for that, and HD-DVD didn’t without increasing the compression rate.
HD DVD further harmed its video quality by encouraging studios to ship movies as hybrid SD/HD discs with a DVD layer for old players and an HD-DVD layer for new players. This provided a single disc that would work for both old and new video players, but each version was limited to just half its full capacity: 15GB for the HD DVD layer and 4.7GB for the DVD layer. This significantly reduced the quality of both versions. Blu-Ray never supported this, and studios have instead shipped two separate discs in the same package for upgraders - each dedicating their full capacities to their respective versions.
The below table shows you the detailed differences between HD DVD vs. Blu-ray

Blu-ray later used some of its extra capacity to add support for 3D, something HD DVD would have had a much harder time squeezing in. You could see that Blu-ray is much more superior to HD DVD in video quality.
