I am using PD 7.0 Ultra with AVCHD files recorded in Dolby Digital 5.1 from my Sony camcorder. After recently updating my product with the latest patch "build 2429a", I am now getting a pop-up error message that says Dolby Digital 5.1 is not supported in my current version and that I need to upgrade my product. When I click on the link provided by the pop-up it says server error or something like that. This was not the case before this update. According to the features and specifications for this product, Dolby Digital 5.1 is supported. Plus, what upgrade is there? I thought Ultra was the highest you can get? Anybody have this happening to them? I also sent an inquiry to technical support to see what they would say.
