[Bug-xorriso] libisofs: unsupported ECMA-119 feature (interleaved mode)

[Jonathan Dowland]

Hi!

Whilst trying to list the contents of an ISO file I have captured from a 
home-made DVD-R DL, I received the following

> ▶ "$xorriso" -read_fs "norock" -error_behavior image_loading best_effort

Note an additional issue that might or might not be related. I was only able to 
partially read the disc image, roughly the first half of the disc read in OK by 
ddrescue, and then I get issues from 0xFB460000 onwards. This happened for 
another DVD-R DL too, so I am suspicious as to what's going on around the layer
change when I read it. But I don't know whether that relates to the libisofs 
error above at all.

If this is of interest to you please let me know.

Thanks!
