yeah its a headache to get it to work becuase even the owners manual is really quite useless, it does in fact support DTS, and I believe what Black mamba said is pretty much the correct way to go about doing things, remember though , have your reciever set to its digital auto , the dvd set to dts and the ps2 set to play dts. If all of these conditions are met then it should play , welcome to a world of pretty logos and slightly better quality.
