So I took the plunge and picked up a new Denon 3808 but I am struggling with the set up as I am very under educated on this stuff. Can any one help me with the following: I Have the following: Denon 3808 using 2 zones, 1 for 5.1 set up and 1 for whole house audio. Sharp 46" D82U LCD 1080P-connected From HDMI monitor out Time warner Cable Scientific Atlanta HD DVR box-Connected w/HDMI JVC DVD Connected with Optical and component Mitsubishi VCR connected with SVHS and analog red/white Yamaha CD connected with digital coaxial Here are my issues: 1. The signal on several of the HD TV stations is constantly switching in and out, from 720p to 1080i to 480i, etc not all just some. Is this a problem with the HDMI cables or possibly the Cable box? On a previous receiver connected via component this did not happen. On this same note, how do you set the receiver to upconvert all the video(dvd(480p), vcr(svhs), non HD tv(480i) etc to the 1080p format - I know the receiver does this. And shuold the TV recognize the 1080 upconverted signal on all sources? 2. The zone 2 system works great but I can only play the VCR, Tuner and CD player, why not the DVD and the Cable box? 3. When I play CD's in Stereo format the Denon display shows FR, FL and SW yet there in no sound from he sub. The sub works fine in all the other surround modes. Thanks to anyone that can assist me!! Go Hokies!!
