I have read a number of posts about the VSX-43 receiver from Pioneer and trouble with surround sound. However, I haven't found an answer for my particular problem and I would like some help. I currently have a Philips Plasma HDTV (about 5 years old), a Cox DVR set top box and a Sony Blu-Ray player all hooked up to my VSX-43 with HDMI cables. I also have a Sony SubWoofer connected with an audio cable. I ran the MCACC setup and all 6 speakers were recognized. If I play a DVD I am getting full surround but when watching TV I'm not getting anything out of my rear speakers. I know the shows are broadcast in 5.1 Surround but am at a loss trying to figure out what is wrong. Thanks for any help out there!
