What is the difference between the "Sony Blu-ray Set Top Box" forum and the "Sony NSZ-GT1" forum? They both state that they're about the combo: Blu-ray/GoogleTV box. There is only one option for buying the latest combo version of the Sony box: the NSZ-GT1, right? Want to make sure that I'm searching the correct product on Amazon. I need an digital-optical-audio-out port, in any case. I already have the Revue, and may be interested in a cheaper option of just a Sony Blu-ray-player-only, without GoogleTV . Do these have digital optical audio out ports?
