DVDA 1 will work fine with files output from Vegas 5. However, there's so many improvements to DVDA2 that I wouldn't want to continue using DVDA 1. End Actions alone is worth the price of the upgrade. Throw in multiple audio tracks, sub titles, etc.... and you'll see how big of an upgrade this really is.
hey John DVDA does not seem to be sold as a separate product and therefore i think you HAVE to upgrade to Vegas 5 to get DVDA2 so to answer your question: 250 bucks
==========
So in other words,
1. DVDA 1.0 considered a premature release by virtually everyone on the forums
2. DVDA 2.0 is a big improvement, but to get it I must:
A. Buy Vegas 5.0 along with it
B. Upgrade to Windows XP or Windows 2000
C. Upgrade my computer or buy another one to handle it
