Hello Joe,

Fantastic 4: Rise of the Silver Surfer is 100% BDJ- only expect for the first play and top menu titles. Thanks Joe, we'll run some performance tests with it. We checked out the other titles you mentioned expect for SP3. They were mainly HDMV titles, we'll pick up SP3 and take a look at them.

Hey Scott -

I'm not sure about all of them, but the recent Disney titles (Cars and
Ratatouille certainly, and I think Pirates) should be almost all BD-J.
Many discs will make the first play title (and sometimes the top menu
title) HDMV so that the player starts up quickly and folks aren't
greeted with a loading screen from the get go. I think some of the
earlier Disney titles, like The Guardian (and maybe Chicken Little)
were a mix of HDMV and BD-J.

A lot of Lionsgate discs have some nice BD-J on them as well. Weeds
comes to mind, and I hear 3:10 To Yuma has some nice stuff on it,
although I haven't seen it.

Cheers,
Joe

Hey Scott,

if you are looking for a disc that has everything done in BD-J, you should also take a look
at Tim Burton's "Big Fish" from Sony Pictures.

It is an interesting disc, because it has animations that are skipped on slower hardware
and eveything runs smooth on all players (which is not true for some other discs.)
If you take a look at it, you will get a pretty good impression of what can be done with
pure BD-J.

Hope this helps.

Cheers,
Björn

Hi Björn,

Thanks for the tip, we like the title a lot. Unfortunately Big Fish 22 titles total and only of them is in the BD-J mode the rest run in HDMV mode, this doesn't include the First Play and Top Menu which both are in HDMV mode. and only one of them is a BD-J title.

We still have to check out Weeds, SP3, Master and Commander, The Day After Tomorrow and Ratatouille.

The titles we have checked are
Cars
All the Pirate discs.
Big Fish
The Decent
Chicken Little
League of Ex..
Meet the Robinsons
Fantastic Four...Silver..

Any other suggestions?

Thanks,

Scott

Hi Scott -

I'm curious about your desire to find discs which are 100% BD-J. In
most cases, the very interactrive content (menus, pop-ups, games,
etc.) will be BD-J, but there could be any number of reasons that
several titles be done with HDMV. (eg bonus that doesn't have a pop-
up, titles used to show region or parental warning cards, dummy HDMV
titles to make sure all BD-J resources get released etc.).

It's also very common (as Bill Foote mentioned in another thread) for
all BD-J playback to happen from within one title, as title changes
have various impacts on the user experience.

Cheers,
Joe

Hello Joe,

We are currently doing a cost analysis document that includes, risks, unknowns, roadblocks, industry standards when doing BD-J development. Part of our document includes ways the costs can go up and ways to bring costs down.
Finding a BD-J only title is one of the areas we identified as a possible way to keep costs down once a library is built, however this might not be true if the performance isn't there on all players including the first generation players.

Just a question. I have heard that discs could be either HDMV (I may spell it wrong) or BDJ.
But here you are talking about mixed discs.
What is the truth about it? Can you make the menus in HDMV and have a BDJ game in the middle?

Hi Francois -

Yes, it's not like HD DVD where discs have to be atandard or advanced.
In BD, you can mix and match BD-J and HDMV as much as you want, on a
per-title basis. (Of course, both BD-J and HDMV can refer to the same
audio/video content from different titles).

Cheers,
Joe

We have come to the conclusion that the reason for BD-J and HDMV to co-exist on a disc is that BD-J is still being improved upon in two ways:

1. The realization of the specification doesn't always mean the BD-J application will perform at a level a viewer would tolerate. Therefore the software community has created two techniques which are now considered best practices: Stitching Images together and manual compositing. This reduces the decode time and it also reduces the rendering time.

2. The CE devices are being improved with ever new generation.

We are hopeful that the players will improve in the very near future so BD-J can be used without the workarounds which are now best practices.

A title that is 100% BD-J is Fantastic 4: Rise of the Silver Surfer. We recommend checking it out, them BD-J work is great, if you have an old player the performance is acceptable but the load time is not.
