I just received this system and it sounds really great.
I have a question though, I have a PS3 and my Scientific Atlanta DVR(Cable Vision) both plugged into the receiver using HDMI cables, and then i have a cable from receiver to TV. However im noticing that if i turn on the tv, the receiver then cable box, on the TV it says "No Signal". When i turn on PS3, ps3 title comes up, also if i unplug the ps3, the cable box comes up. So it looks like i can't turn on my cable box when another component is connected. What am i doing wrong? Also is there a firmware upgrade for this unit?
