Ouch - I'm running into the issue that when I play a full Bluray disk on my computer, sometimes the menu "music" is completely loud static, I have to mute it until I hit the play button - once the movie starts, the SP3 locks on and Dolby TrueHD plays fine.
I've had to resort to setting a script to mute the SP3 anytime I'm playing Bluray menus, just in case. Wish there was a fix for the DTS / Dolby switching issue that I think is the root cause here, based on the info in the thread? Stan, is there any logging or troubleshooting or debugging we can do to pin point why this occurs?
