DVDA is well known for its inability to work with certain burners, interface types, or certain media types or certain burner/media/interface combinations.

In fairness, it's not entirely DVDA's fault - from all appearences, there's no first or third party conformance tests to make sure burners correctly implement the communication interface (or if such tests do exist, the burner manufacturers don't care). As a result, in order to ensure complete compatability with every burner, the folks engineering DVDA would need to test every single possible combination themselves - a very large job, especially for a product who's primary purpose is to author DVD's - not burn them.

My suggestion? Accept the fact that burning with DVDA doesn't work with your configuration, and use something like Nero to do the actual burn of the project.

If you want, you can formally report the problem to Sony by clicking on the support link at the top of the page - but history seems to suggest that the current situation will not change anytime soon, and certainly won't for 2.0 (it appears that the only release that gets engineering support is the current release - which is 3.0).
