They probably support both. I think there was once a patch for libdvd*
to use both, but I don't know if it was applied or if it was how to
select between them.

Na, that is around the end of the DVD. I'd guess the UDF file
system structures may have pushed the size to be too large for
DVD. Or you had just bad luck (I guess the chances for bad luck
are quite a bit higher for the combination second layer/outer
border of disk).
