[Keith Gray] “want to use the software thats best and most up to date to make my job easier.”
As far as I know, DVD authoring software on a Mac is pretty much limited to DVDSP and Adobe Encore, both of which are no longer being updated. I think the general consensus is that although they’re still widely used, DVDs are becoming less and less mainstream. Also, if you’re using the very latest Mac OS you may find that neither of these work as expected, if at all. Good luck.
