I hear you. I had the same problem up until a month ago. I have a Pioneer plasma too and was using and ATI 7 channel amp and a Sherbourn 7010A processor. It sounded really good, but there was always the control problem for the rest of the family.
My solution was to sell the ATI and Sherbourn and buy a Pioneer receiver. I purchased the Pioneer VSX-94TXH from Ebay and a SR+ cable from Pioneer. The SR+ cable allows the receiver and TV to talk. Se everything up in the receiver once and off you go. The units both change inputs when needed. If i want to watch tv using the Pioneer plasma's tuner. Once push of the remote button and there it is. My family now has no problems.
The sound quality didn't change. The pioneer receiver sounds really good too. I have a HD-A3, a Playstation 3 and a DVD/VCR combo going through the HDMI inputs of the Receiver. It is really nice to use one cable for the video and sound and the ability to decode Dolby HD.
A Pioneer receiver and SR+ cable from Pioneer should solve your problem.
