DVD-Audio burned from ISO WILL NOT PLAY

[Tabbycat]

I've burned two different ISO images of DVD Audio discs using the latest version of ImgBurn.

 

I used Memorex DVD-R blanks, and two different computers -- an HP laptop (XP) and a newer Sony (Vista Business).

 

The discs both burned and verified okay (if very slowly), but are not recognized at all by two different players:

 

Pioneer DVD-A/SACD player

Sony PS3

 

 

What's wrong?

If it passed verification without errors then the disc was properly burned and is an exact match to the ISO image. As it doesn't work, the ISO image probably is wrong/damaged. How was it generated?

Got one off the Noid, one (Diatonis) from the band.
