I find it hard to believe any device that can read a DVD doesn't support
UDF. That would be a very dumb design choice.

UDF was designed for read/write use. iso9660 was very much designed for
read only. It is much more complex to update an iso9660 filesystem
after it is created. It just wasn't meant for it.
