As many of you noted, PowerDVD Ultra decodes DTS-MA to 5.1 discrete channels. On a 7.1 channel audio system the discrete audio encoded for the side channels would not be decoded. Of course, the left, right, center, rear and sub/LFE channels are still decoded.
Of course, PowerDVD is capable of extracting and passing the encoded audio from the Blu-ray disc directly over a protected audio path (HDMI 1.3 on supported hardware) to an A/V Receiver which can decode the full DTS 7.1. This is supported on ATI Radeon 5xxx series graphics and Intel Clarkdale /Arrandale systems, as well as Auzentech X-Fi HomeTheater HD sound cards.
We understand that there are some customers who would like PowerDVD to decode the full DTS-MA 7.1 in software, passing the 7.1 channel LPCM to the audio chip/sound card. I'm discussing this question with our Product Managers. The challenge for us is in understanding the cost/benefit, versus other requested features. The cost is not insignificant (both direct and indirect costs), and it is hard to justify adding a significant cost to every copy if the % of customers wanting or needing this feature is very small (especially given the DTS-MA hardware decoding options). Of course, we strive to offer the best-in-class, so we will continue to investigate the issue, to see what makes sense, and what can be done.
So as not to clog up this thread... please send me a private message if you are one of our customers that feels that DTS-MA 7.1 channel software decoding is essential for your configuration. A quick description of your configuration (sound card / chipset, graphics card, AV Receiver or audio system) would be helpful.

If you want Cyberlink to up DTS-HD MA from 5.1 to 7.1 using PowerDVD's internal decoder, please let Tom know so he can work out how much demand there is for it.....
