I have very little experience making DVD-A (usually do DTS discs) so maybe my question has an obvious answer that I am just missing. I DL'ed a double album that was in the form of two DVD-Audio ISO files, one for each disc. Both ISOs are aprrox 2.3Gs each. It would seem to me that 2.3G + 2.3G = 4.6G and that the total program should be able to fit on one 4.7G disc.
To test my theory, I extracted the ISOs using MagicISO, each to a separate folder. Then, using DVDA Explorer I extracted the six wave files for all the songs on each disc and put them in new folders, again one for each disc. Next, I renamed the files using Channel Rename to prepare them for use in HD-Audio Solo. (This was a 3 step process due to the differing naming schemes used by the previous programs, but easy none the less.)
With the channels renamed, I assembled a layout in HD-Audio Solo of all the songs from both folders. I checked to make sure I had all the DVDA settings correct and proceeded to write a new ISO. The program immediately gave me a warning that I had exceeded the maximum size for a DVDA by over 4,000MBs.
At this point I figured that I just cut it too close, knowing you can't totally use all 4.7G on a blank DVD disc for data - some has to be reserved for essential files (headroom) to make the disc work. HD-AS gave me the option of continuing anyway, so just to see how close I came to getting the entire program I let HD-AS go ahead and create the ISO image. To my surprise, the resulting ISO is nearly 8Gs! I didn't add any pictures or fancy menus or change the sampling rate (88k) or bit rate (24b) at any point in the process. How did it grow so large? Did I miss a step in the process?
