Menu based Bluray read as data disk
on Jun 20, 2014 at 1:05:57 am

I has doing a test burn of a project onto a Blu-ray re writable disk. When I tried to play it on my Samsung 'Smart' player it suggested that it was a data disk & asked me to select music, video or pictures. I thought at first that the problem might have been the player since it had just undergone a firmware upgrade. So to test this I took both an old DVD & a previously authored Blu-ray & they played perfectly.

I had made a couple of small last minute changes to the project before It was rendered out. I was wondering if there is anything that could have altered the burn to suggest that the project has anything other than a menu based disk?

Thanks in advance

Was the other Blu-ray disc also on re-writable media? It could be the re-writable media that is making it think it's a data disc.

The other had originally been written onto the same Blu-ray disk & when it worked OK I just burned it onto a normal disk.

Thanks in advance

Yea, but you changed the firmware so maybe the new firmware is acting strange with BD-RE discs? Try burning the old project back to the BD-RE disc and see if it still works. I don't think there is anything you could have done to your new project to make it not be recognized as a menu based disc. You can always take it to a store and try their Blu-ray players just to check.

BTW, Blu-ray has had it's share of dropping support with firmware upgrades so it's not uncommon that something will stop working when a firmware upgrade is applied. Some manufactures did drop support for menu based discs on "burned" not "pressed" media as a feeble attempt at thwarting illegal Bu-ray copying. I think they have stopped that now but that's an example of how silly this whole Blu-ray licensing things has become.

You would think they would have learned from the real-world of CD's and DVDs. If I can see it (hear it), I can copy it. The Blu-Ray encryption was sold as absolutely unbreakable, and even if it was, broken encryption could be modified through a database update on the newer BD discs themselves. Ever wonder why it takes so long for a BD player to start a new disc? The player is updating its' database of encryption keys.

It took only a month for the BD encryption to be cracked. Again, by a kid (like the CSS crack on DVDs).

Yet, they persist, thinking they are somehow preventing pirating.

They haven't learned anything. We don't watch Blu-ray's anymore at my house because they are so slow. I have better things to do than wait 5 minutes while a Blu-ray disc spins up and finally gets to a menu. We went back to buying only DVD's.

I would agree with you inasmuch as all formats seem to be just transient. Blu-rays never sold enough to warrant the investment. Both Blu-rays & DVD's will eventually completely make there exit as people are finding it easier to create home networks & have media players.

I also agree that the Blu-rays are very slow to start & can sometimes be very noise until they start playing.

It would be a pity though to loose the features of Blu-rays like chapter markers,multiple audio tracks & subtitles that you can turn on/off. MKV allow for some of these features to be retained & played by a media player sourced from DVD's.

I seem to recall reading that there is also some programs around that can do the same thing with iso files for both DVD's & Blu-rays but I can't recall its name. The good thing about this is that you might be able to keep all of the features like motion menus & scene selection menus.

As for my problem disk I had a lot of problems erasing it. I thought it might be best to just give the project a new name & just re burn it. I found that DVDA just wanted to use my old ISO files. I eventually copied the project & the preview said that the disk would be erased. It didn't erase correctly since I had part of current project & older data as well. I erased the disk in Windows & another authoring program as well & DVDA still said it wanted to erase, but I finally had it burn OK. Presumably I had a faulty disk.

Thanks in advance

I don't see this happening any time soon because manufacturers seem to to be incapable of creating a media server. Everyone expects you to run a PC to watch TV. That's never going to fly. I have a Buffalo Linkstation NAS that runs 24/7 serving up files in my home. If that thing could be a proper media server, I would be all set. It supports DLNA and tries to be a media server but it falls far short. I have an Apple TV and Apple doesn't seem to have a clue how to solve this either. They also want you to have a Mac open running iTunes. Why is it these big companies are so clueless when it comes to streaming home media? This isn't a hard problem to figure out and, IMHO, Apple is in the best position so solve it but they don't seem interested. :(
