VideoStudio :: Cannot Burn Disk In Dolby 5.1 X6 Ultimate Or X4 Pro

I recently purchased VS X6 Ultimate. I had been using X4 Pro. I chose the full install not the upgrade version of the software.

While using X4 for a while, the program would not burn a BluRay or AVCHD disk in Dolby 5.1 no matter what settings I chose. It would only burn in "Stereo". VS X4 DID burn these disks in Dolby 5.1 for a long time then it just stopped. I always selected Dolby 5.1 from tools or settings menu at the top of the program (I forget which one as I am not at the computer I use for VS). Also when burning my disk I select Dolby Digital 3/2 and 448kps.

When the disk was played back in my BluRay player, it only showed two channel stereo.

Then I upgraded to X6 Ultimate and the same thing happens! Yesterday I burned a short 16 min video consisting of mostly still photos, some HD video, and music tracks and transitions. I made all the "correct" selections to produce in Dolby 5.1 and the disk, when played in my BluRay player is again in Stereo. I have tried other disks to ensure my BluRAy player and home entertainment system is not faulty. The system readily shows Dolby 5.1 and 7.1 for studio produced disks.
