I currently have a prototype Hauppauge Colossus HD PVR in my development HTPC and wanted to start a Q\A thread here at Missing Remote. Note, I am using a prototype board so my experience may vary slightly from the production boards but not significantly. So far it has been stable. I am using two boards, one with digital audio and the other with stereo audio to compare and track potential stability differences. There are four inputs. 1- HDMI; 2- A dongle that provides either component video + analog audio or composite video + analog audio; 3- TOSLINK SPDIF (digital optical) input; 4- IR receiver (shared with the IR blaster).
