Connect another set of analog video and audio outs from the sat receiver directly to your TV. This will bypass the receiver and allow use of the TV speakers, but only for sat viewing. (If your TV can accomodate more inputs, you can repeat this procedure for the DVD player, too.) Keep in mind that you may have to use a lower quality output (i.e. s-video vs. component and stereo analog vs. digital) but it works well for those times when quality is not an issue.
