nah, the dvd player itself had 5 speaker outputs, so i guess it had a built in amp. it seems silly that it could decode pro-logic ii from dvd's but not from it's own inputs, but nevermind.
5.1 didn't bother me too much with cube, so i pretty much gave up right away when it didn't work. but wii games seem more immersive, so i'd like to get the best playing experience in 12 DAYS TIME! :D
