I haven't seen this discussed too much anywhere, but Tiger's disc burning from Finder now formats discs in a Mac OS Extended/UDF dual file system. In Panther, disc burning used the ISO 9660 standard. So it is now possible to take existing VIDEO_TS projects and burn them directly in the Finder for set-top DVD Players.
The only drawback is that these discs will mount as Mac OS Extended when inserted into Macs. As such, OS X's DVD Player will not recognize them as DVDs, unless you do an 'Open DVD Media...' from the File menu. Still, they play great on my standalone DVD Player. Goodbye Toast!
