Yes,pre-recorded DVDs are ISO 9660 format. It is writable DVDs that use UDF. So you can mount a DVD and read the encrypted files under FreeBSD. And, if you have DeCSS, you can, in theory, decrypt and view them. The problem is that 9660 is NOT a good format for read/write operations, so UDF was developed to take the "nature" of writable optical media into account so that they can look much like a slow magnetic disk.
