The built-in authoring options that come with Premiere -- both the $500+ Pro, and the sub-$100 Elements -- are not very good, no. Few people use them. Premiere is great for editing, pretty good for exporting, but it's simply not authorware.
In this field, DVD Studio Pro is very common. Yes, that means most place have both Mac and Windows systems. (They're just tools! No rule that you can only pick one!) But that's really the only one on a Mac, aside from (again) Premiere. DVDSP is now part of the Final Cut package, bundled together.
There's a number of options on Windows, be it Scenarist on the high end, Sony Architect in the mid range, or Ulead DVD Studio Pro or DVD-Lab Pro on the low end (yet still very much pro software, $200+ MSRP). As technology ages, and time goes by, the options are less and less. But the "old" software from the likes of Ulead/MediaChance still works fine. Better than consumer software, old or new.
We use DVD Studio Pro, Ulead DVDWS2, and TMPGEnc Authoring Works (Blu-ray, menu0-less DVD).
We NEVER use the templates. Those all suck, regardless of price range. My menus are nice.
