If your dvd player is capable of playing sacd's and you have connected the six channel outs to your six channel ins on your av amp then you shouldn't have any problem.
If your dvd player doesn't play sacd's then you might still be able to play as a normal cd if it is a hybrid disc. Hybrid discs have two layers one for sacd and one for normal cd play back. If the disc is not a hybrid and if your dvd player cannot decode sacd then I'm afraid you've bought something you cannot play. Had a quick look for the Peter Frampton sacd and the only one i found was not a hybrid.
