I have used Pinnacle Edition DV500. I am currently using it while my VV4 academic version is shipped from Academic Superstore. It has many features; however, it has a deep learning curve. The user manual and documentation is poorly written and there is hardly any additional materials or tutorials. Good luck.
My dealer gave me a demo CD of the 4.5 Edition. It is trying very hard to simulate an Avid look and feel... Very stuburn in terms of learning - everything is buttons and nothing is labled - but it does seem to have some nice options.
Just not itutive. Lets face it; Nothing out there right now can touch VEGAS 4
