Default BluRay Disc Storage Capacity Hyped?

I am a neutral supporter but was wondering if their was a way to check compared to the average total size movies are presented in HDM.

HD-DVD- 30 GB
Blu- 50 GB

Well if it is so important does bluray actually use that amount on any given disc?
ANybody have a PC bluRay drive to tell the space being used compared to the 50 GB. I am very interested to know the results.

The better question is, why is Toshiba trying to make a 51GB disc? For the fun of it?

The moon race. The arms race. The disk-space race.

I have a funny feeling that disc space thing is the reason why so many more Blu-ray titles have lossless audio tracks as compared to HD DVD.

Depends on the title.

Disney stretches BD to the edge.... 40+ GB isn't uncommon for them.

I don't maintain a registry, but I'm sure somebody else on this forum does. I'm sure it varies, but logically studios optimize to the available disc space. I don't know how many HD DVD 15GB discs are used, but I would expect 30GB would be the norm judging by the frequency of 50GB disc use I'm seeing by Blu-ray exclusive studios. If they didn't need 50GB, they'd use the BD 25GB discs, I'm sure.

Good question. I've wondered this as well.

If you use AVC with Dolby TrueHD which according to reviews gives the same audio as uncompressed audio how much of the BD50 is used on an average.

We know that MPEG-2 & uncompressed audio take more space but you get better video in my opinion with AVC & Dolby TrueHD & uncompressed audio are pretty much a wash.

It would be interesting to compare the average space used on HD DVD vs Blu-ray.

Disney does have the best transfers & it's fun to watch the bitrate meter but if Disney used Dolby TrueHD or DTS-HD MA instead of uncompressed sound it would be interesting to see total space used.

Is there a website to go to see the file sizes of the movies on HD DVD & Blu-ray?

Marine,
Yep I wondered my self. It could be a good idea for comparison purposes. It would be a good comparison if a website would show the breakdown. Also maybe if they listed them on the HDM DVD back of the boxes.

space is hype. i agree... pcm and mpeg 2 are a waste of space if you have more eficient codeacs that can fit 5 hours of 1080p video and great sound on 30gb... island fever 4 has 5 hours of 1080p video + 5.1 sound. truehd is a more efficient way of having losless audio... it'd be like ripping a 750mb cd on your hard drive when a 320kps mp3 is more efficient and sounds great.
