I'm a registered and (so far) satisfied user of VV 3.0. I'm thinking of upgrading to 4.0 and DVD Architect but my chief worries are 1) the financial stability of the company and the possibility that VV might go poof 2) the technical stability of VV 4.0 and my experience with upgrades: they tend to be buggier and more bloated than the glorious version I fell for in the first place.
All advice appreciated.
