It offers complete authoring and burning solution that DeepBurner/DeepBurner Pro lacks. You can still create VideoDVDs with DB Pro but the vildeo files need to be authoerd first. And that's when DeepDVD Movie comes into place.
And there's no need to buy Beta version, there's a license key available for Beta testers. See here: http://www.deepburner.com/?r=news&id=54
Would appreciate any feedback.
