Theo,
the DD bug is as follows:
If you are receiving a DD 5.1 source, and you are pressing the Dolby button on your remote to switch through DD modes, it gets stuck at PLII Movie.
If you are receiving a 2.0 feed, it gets stuck at AC-3.
To continue switching, you must go into the Mode Select menu.
For DTS, I have only noticed the bug to be with DTS 5.1 sources. I have never tried upconverting a 2.0 source, as I have no DTS 2.0 sources. Mind you, I have some Pink Floyd in 4.0, I'll give that a try.
If you are or are not having these bugs, I'd be really curious to know. In fact, so would Emotiva, as they are working on fixing them.
Thanks Ted,
Ravi.
