Would be nice to know what the resolution to this was !
I too just bought a retail blu-ray dvd burner/player 3d capable which came with a BD solution package and can not use the burn dvd from files function without just getting to the "upgrade option" and no further.
So is this function "removed" ???
I have an older package that I got a year or 2 ago with an earlier drive and the version on that package does allow burning from files at least to a regular dvd.
