Do I have to have a TV that has DLNA functionality to stream music from my PC? I am looking at Samsung Plasma TV's and the 51" with DLNA costs R12K (PS51D550)- the one without (OK it is HD Ready and lacks some other features, none of which I need) is R7K (PS51D450). I sit too far enough away for Full HD to really make a difference. Maybe I can just plug in a USB drive and the TV can browse that? Files are on iTunes - ALC.
