Hi do Blu-ray & HD-DVD have equal same picture?

[tito]

Hi both Blu-ray & HD-DVD formats supports 1080P & 7.1 Channel. The only difference is that Blu-ray has 50GB & it's from Sony Co. & HD-DVD it has 30Gb & from Toshiba Co. Yes I do know that HD-DVD lose the format war but, I want to know do Blu-ray & HD-DVD has the same 1080P picture? Many people say that Blu-ray picture has ultra HD picture greater then HD-DVD picture? Is that true? Thank you!

Note: During the format war, I use to supported both formats.

The only thing that I do not like Blu-ray is that some movies have grainy picture but, HD-DVD it has clear picture.

HD DVD wasn't from "Toshiba and Co." - it was just from Toshiba. They made all the HD DVD hardware parts for any other companies HD DVD player so that they could be sold at a loss.

Blu-ray was not just from Sony, it was designed by Philips, Sony, Pioneer, Panasonic, Sharp, JVC (VHS founders), Hitachi, etc., etc.

Blu-ray is capable of better picture but it can only be shown when a studio encodes specifically for both formats. Warner Brothers always encoded for HD DVD first and then ported over to Blu-ray, encoding for the lowest common denominator.

R&B Films however did their Nature's Journey release encoding for both formats. As a result of the inferior bandwidth of HD DVD, only the Blu-ray got a lossless audio track and the average bitrate was substantially higher. This still isn't noticeable to many people outside of those with a 100" screen and 1080p24 projector, but it nevertheless still exists.

HD DVD was perfectly capable of a great picture and pulled it off many times, but the problem lay where people weren't looking. Because of the 30.09 Mbps limit for audio+video combined, more time was needed for each HD DVD encode. Were studios to require 1080p and lossless audio for each disc with the goal of a release schedule as prolific as DVD they would never be able to do it with HD DVD. They would either have to drop the lossless audio to allow for more space for the video so that the encoder works more efficiently, or they would need to go down to 720p resolution which is really what they must have been thinking when they went with 30 Mbps vs. 48 Mbps on Blu-ray.

That extra bandwidth is the key ingredient - capacity has very little to do with it. Most people don't mind turning over a disc. The 48 Mbps allows for lossless audio tracks in multiple languages and still 40 Mbps room for video encodes, allowing an MPEG-4 or VC-1 encoder plenty of extra room to encode difficult dark scenes or scenes with lots of grain.

The format most capable and ready for mass market adoption of 1080p won the format war.

Blu-Ray is not as good.
