Im curious, im lookin to buy a HTIB(home theatre in a box), particular the toshiba SD-C67HT, or samsung HT-P50. The units both have HDMI connections which will allow me to connect it to my Philips 30pw9110d HDTV, and they both can perform upconversions from uncompressed video to 720p and 1080i. I wanted to know a few things, 1) if i connect other sources to the HTIB will those sources get upconverted visually or is that for the DVD portion of the home theatre and 2)if i'm watching TV and not a DVD, does TV audio outsource through the HDMI connection back to the HTIB or will i need to connect a coaxial or optic cable to it from the TV. (i heard that HDMI work 2 ways in/out out/in)
