Unfortunately 188.8.131.52 is the latest version right now and it won't work. But it's not surprising, this BRD was just released a few days ago. Maybe I'll just try this with another movie. It's just dicking around now anyway until there's affordable BRD burners and media.
Has it been pretty well established that with this method, and possibly BRDGen, that the ability to burn movie backups is all but guaranteed once we can buy burners? It seems that way doesn't it?
