Hi Everybody! I have just made my first major Home Cinema/Plasma purchase and have a quick question about the Denon. I've had it up and running most of the evening (about 6 hrs) and just come to turn it off, I've noticed the AV reciever is really hot by the vents. Just about bearable to place my hand on, I would like to know if this is normal for AV recievers or should I be worried? Its on my carpet floor at the mo while I get a rack to put all the kit on, nothing was placed on top of it and plenty of room for air flow etc. Also, I have (long story short) a tv tuner box which is plugged into the 550 via s-video and composite? audio? (the phono red and white ones) I can watch TV and listen to sound ok, however when I change to DVD and play I can still hear the TV sound AND the DVD sound at the sametime? Any ideas why?? incase anyone is interested... here's whats I got... NEC 42XR3, Denon DHT-550, Panasonic DMRE95HEBSM. Thanks for looking and if anyone is thinking about getting any of the above, or indeed any comments (good purchases???) i'd be happy to answer any questions. Cheers!
