There is something fishy with the AMD card and drivers...
First off you got totally ripped off on that cable. If you can still return it please do. You can get a high quality cable that can do all of those things from monoprice for $20. Yes even a 20" one.
Second yes your 6950 does support all of that over HDMI, but it needs to go into a receiver that supports those codecs over hdmi as well. You can't plug it into your tv and expect dolby true hd.
As stated above some tv's can pass regular DD and DTS through their optical jack to your receiver. This is the method you need to choose. It also depends on your player and how you have it setup. You want to be bitstreaming the audio not letting windows turn it into pcm.
What player are you using? Or is this for games? The problem still might lie in the fact that your gpu sees the tv as a 2 channel device.
