We have the same htib model (kasi ikaw nangdemonyo sa aking bumili rin ako) anyway Ive been using my PS3 as a Blu ray player and the PS3 is connected to the htib thru optical.so far no problems yet regarding audio, but ofcourse I only have a handful BD collection and this is the first time Ive learned that there are DTS only format
The Wii is not 5.1 compatible but using the htib with it, the wii actually decodes the sound using the red and white analog to make it surround.try playing wiisport tennis and you can hear the rear speakers
