not true.

you can just add ISO9660 filesystem metadata, getting two 
different filesystems of which both's metadata puts to the same place so 
data is shared, getting more portable disc. and getting faster access to 
files as UDF isn't as efficient.

but UDF is NOT an ISO9660 extension. UDF can live without ISO9660 
filesystem at all.


if you used UDF programs in windoze, they all have option to add ISO9660 
filesystem (just generate metadata) and fixate - after whole disc is 
filled with data.

mounting, mkisofs -dvd-video works fine
