Neil,
Yes, I mean on a Mac. Apparently my choice of alliance in the computer wars means I have made my bed and now I must lie in it.
I hadn't checked on Blu-Ray yet. I assumed it would be at least a little longer before the burners, the authoring software, and sound and video building applications and editors would become affordable. I know that Toast has offered support for BR video for a while now, so I guessed it wouldn't be long before Mac users could begin to explore all the possibilities of BR. Obviously, as BR allows for uncompressed audio, it would offer a decent possible replacement to the dvd-a disc in the future.
OK, so universal discs are definitely a dual layer thing? It sounded more like a double session thing with the player seeking out which session and its contents were applicable to it (just like a computer will "see" and be able to use both data and audio sessions of a mixed mode CD, but a regular CD player will only "see" the audio session). I know that DW Bronze does not do dual layer at all. If it's a DL thing you not only need to worry about how much total space of the disc the two _TS folders will need but you need to have the second layer be less than the first. I also thought there was no such thing as a DL -R disc. I've never been clear on the difference between - and + anyway.
As for image files, if I understand you correctly not only does the DIM, ISO, etc. need to be constructed properly (i.e. with DVD Studio Pro, Sonic, DW, WaveLab) according to the type of disc you wish to make (and embedded with, for lack of a better term, some kind of identifying information--again if it's not a flag per se, is it just specifically named files in specifically names places? There has to be some bit of data in there somewhere to tell the player what kind of disc it is), it also must be burned with authoring software (Toast, ImgBurn, Burn) that can actually DO that kind of image file. Neither Toast, at least my current version of it, nor Burn can do the universal disc ISO that I mentioned I acquired, neither can they do dvd-a discs from an ISO or an AUDIO_TS folder, although Toast does do dual layer dvd-v. Neither app will just burn any disc based on the content of the ISO; it has to be familiar with the type of disc in question apparently. I've asked SourceForge about the Burn problems because it is not necessarily stated that it will burn either universal discs or dvd-a discs from an AUDIO_TS folder, although it will apparently do dvd-a from regular stereo audio files.
So with DVD Studio Pro I can obviously make the correct dvd-v portion and with DW-B I can make the correct dvd-a portion. I need a Mac image file construction app to either create a universal disc image or merge a VIDEO_TS folder with the DIM file that DW-B would create and an authoring app that will correctly burn the resulting image file, correct? Because, obviously the ISO alone is not sufficient for just any burning program.
Hello.
Universals are not always a dual layer thing - just very common.
Not even a dual session thing either, as you only burn once. What you do have to do is build 2 titles though - the Video_TS & the Audio_TS.
You are correct about the control over type of titles loaded is indeed based on certain files being in a certain place - for an Audio_TS to load in an Audio capable player, there must be an AUDIO_TS.IFO file located within the Audio_TS. If the player cannot find this, it will look for VIDEO_TS.IFO in the Video_TS etc.
Naturally, a non audio capable player will not look for the Audio_TS at all.
AFAIK, DVD Studio Pro cannot create a properly formatted Video_TS for DVDA use - it's an abstraction layer tool, and will create dummy VMGM files & VTSM files that should not be there, and additionally it will almost certainly use illegal commands in the construction (Pre & Post commands especially). Only way to know for sure is to take a DVD-SP created Video_TS file & attempt to import it into Sonic or Chrome. Maybe you could send me one and I will try it & see.......
As far as universal titles go, I think you are screwed with a mac unless there is a burn application that can do what IMGBurn does.
As far as I can tell, all you can do is an audio-only title from Bronze, which is of course fine for personal use.
