If I author a Blu ray disc, the disc won't play in my Samsung BD-P1000 Blu Ray player.  Standard Def DVD seems to play fine, but it won't play the HD BD-R.  My Samsung ejects the BD-R and says "This Disc cannot be played".  It plays fine if I play it in the BD-Recorder in my PC that I use to burn.

What am I doing wrong?  I also have Power Professional, and it authors BD-Rs that WILL play in my Samsung, but DVDitPro HD doesn't seem to work.. Is there a setting that I am missing?

Thanks

R

I also noticed that the BD-R that DOES play is in a BDAV folder on the disc and the one Roxio authors that does NOT play on my player is BDMV.

???

I have used a Panasonic DMP-BD10 and it plays BD discs made with DVDit Pro HD...

panasonic works.  

1st generation samsung without firmware updates works.  the firmware update made it so that BDAV discs on BD-R work, and BDMV discs on BD-R do not work.  Samsung does have an "authoring" firmware that they provide to authors on a case by case basis.  Unfortunately, I do not have contact information for trying to track that down.  

Amendment was passed fairly recently to the BD spec allowing BDMV on BD-R.  The support of that is optional but will likely be adopted by all/most manufacturers as time goes on.

The situation is not too different from the early days of DVD-R in DVD players.

Panasonic is working with BDMV and DVDit Pro HD, but no with BDAV like Cyberlinks PowerProducer BD Edition

My Samsung is just the opposite..  It plays BDAV but not BDMV.

Can the write format be changed in DVDitPto HD?

No, DVDit Pro HD is always BDMV...


What i have also seen on the Panasonic is that it does not Play Dolby Digital Audio, PCM Audio only... or is it a setting problem?

Scott (or anyone else who might be able to clear this up for me),

On the whole "BDMV on BD-R" issue: after reading various web-boards, I was given the impression that the players were not playing back these discs because they don't support 'un-protected' BDMVs on BD-R.  

1) Is this correct, in that it's the 'un-protected' part that's causing the issue?  If yes, then will adding AACS copy-protection during authoring avoid this incompatibility?  Or, is there some licensed rights-management protection one would need to purchase?

2) If it is the BD-R part that's causing the problems, what other formats of discs are there (ie. what are the studio's using?)

3) If it's the BDMV portion, what other formats for Authoring are there for Blu-Ray (ie. what are the studios using?)

Or finally:

4) is this struggle to put out universally playable Blu-Ray Discs not possible without $50,000 in software/ hardware

Thank you,

Dylan

meebl,

OK, so here is the deal.  initially, in the BD spec, there is no support for BDMV on BD-R.  Perhaps because of piracy concerns?  In June, there was an amendment to the specification to allow personal BDMV content on BD-R.  That amendment is optional, but it is expected that many (perhaps all) of the consumer electronics manufacturers will adopt the feature.  This is not dissimilar from the way it was with DVD-R ten years ago.  Today, there is support in Panasonic, unmodified first generation Samsungs and (I hear) Pioneer players.

So, to answer your questions

1) yes, it is unprotected BDMV that is being blocked by the players.  no, you cannot add AACS to a BD-R.  just as you cannot add CSS to a DVD-R (up until recently)

2) the studios use BD-ROM, but they test on burnables in all of the available BD players.  They have firmware that will play back BDMV on BD-R

3) the two forms of Blu-ray right now available for burning to disc are BDMV and BDAV (high, high end tools can do BD-J), BDMV has menus, interactivity, alternate audio and subtitle tracks, and everything you have come to expect from DVD.  BDAV does not.  I believe BDAV also has a limit on the bit rate and maybe the frame rates and aspect ratios.  Many of the players will play back BDAV.

4) no.  $50,000 software would not do you any good here.  you can go to replication with DVDit Pro HD.  it will create a CMF image with AACS copy protection and you can go to a replicator and create BD-ROM discs.  Any BD-R create with a high, high end BD authoring tool will have the same issue in BD players.  Those authoring facilities may find a way to get the firmware that will play back those BD-R discs, but without that firmware their discs will also not play.

Thanks for the info Scott!  I get a clear picture of what's going on now... just wish we can let SONY know that we want this...

The PS3 will not playback the BDMV but will BDAV (though chapter stops don't seem to work using the Cyberlink stuff).

Thank you very much Scott, that's a HUGE help in wrapping my mind around this Blu-Ray Beast.

I am curious about one thing, though, you mentioned that AACS copy protection can't be added to BD-R discs.  On the products for DVDitPro HD, AACS copy-protection is listed as one of the output features.  Is this a mistake, or did I miss something?  Or is this solely an image file feature that I wouldn't be able to make use of without having the disc burned by a replication facility?

Thank you again for the detailed breakdown.

Can anyone read the tea leaves and offer a guess as to whether a future firmware update could enable Roxio BD-RE playback on a PS3?

I've tried to email Sony support but I get the canned response "the PS3 can play the following.." so I was hoping Scott could push some buttons  :)

I guess we can hope that it will be fixed for the "big" March update that is rumored to happen...

be assured, we are pushing, but the more pressure from the consumer level for this type of support, the better...

Is there a particular email or site we should voice our opinion?  Seems like the PS3 support site/email is not really the right spot since I just get the "canned" responses from there.
