I use it all the time. It is based on the same compiling engine as Scenarist which is currently the defacto authoring standard. It allows for the dvd spec max of audio and subtittle streams, has a very intuitive storyboard display for linking menus and video assets, and has one of the fastest compiling speeds when you finalize your project. It has had a recent price drop (most likely because of what is about to come out later this summer from Adobe and Apple), so you can get it for less than half of what I paid for it. It will only do 2 channel ac3 encoding, but you can batch process your audio conversion. It doesn't have any templates for menus, you have to create all of your assets outside of the program. If you can wait a month or two, Adobe's Encore will be out and looks very promising. You could get a relatively cheap Mac G4 and DVD Studio Pro 2.0 (<$600) due out this summer as well, and the buzz on this product is that it will bring Hollywood level authoring at prosumer prices (it's based on Spruce Technologies Maestro authoring app that was bought out by Apple a couple of years ago).
