Unbox works just fine for Amazon, however, you cannot use Unbox normally to create a Riffed Movie with combined track.
Also, Unbox has about a 1.2 second delay after the logo goes down. Hold off pressing Play on the Riff for that amount of time and you should sync just fine!
Lastly, if you plan on utilizing Unbox and WMPlayer and doing other things (like I am), I would recommend increasing the Priority Order from the Task Manager on wmplayer.exe and ADVWindowsClientApp.exe. I have these set to High and it works very well. I love the Hateful comments towards the mumbling and filling of the movie with absolutely nothing.
Mary Jo Pehl is doing great, and I'm only 35 minutes in
