Steve, it probably will not work. The issue is that the hi-res channels are probably outputting Dolby Digital 5.1 or even DD2.0 and not a stereo PCM digital signal used by your DAC.
If you can configure your TV to only output PCM, that would solve the problem, but I'm guessing that there is not an option to select PCM only.
If you have an HT receiver available, try plugging into the receiver and see what kind of signal it locks on. It will probably be DD 5.1, 2.1 or 2.0 and you will know you are out of luck.
