just bought a ps3

[chris1985]

hey there, i just purchased a ps3 for blu ray with spiderman 3 and then i picked up resident evil extinction....truly amazing....Im very impressed with the picture quality compared to standard dvds....I have a couple questions though.....right now i have my ps3 hooked up thru HDMI, but i have a 5 disc dvd changer with suround sound....Id like to get my blu ray's sound thru my surround sound???? is there anyway i can do this????

also i want to mail in for my 5 free blu rays...but they require the origiinal upc code...what happenes then if you have to return your system?? the store wont let you return it without a upc code right????

Thanks for the help in advance!!!
