I have started to copy my DVD-Audio discs to .ISO's, and so far, no problem... I assume that when I pick Clone/Burn, I also have to click the Advanced Settings and make sure that "Copy Video-Disc Data Only" and "Copy Original IFO Files" are both unchecked, as DVD-Audio discs have files in both the "AUDIO_TS" and "VIDEO_TS" folders. I have checked the .ISO against the disc itself, and it appears to have copied the above mentioned files from both directories. I haven't tested the files on my Dune HD Base 3D media player yet, but when I do, I will post the results.
