Very timely post (for me). We too have an analog receiver and digital TV. We want to hook the TV to the receiver so when we watch music shows the sound comes out the speakers hooked to the receiver instead of the crappy TV speaker. We spoke to a couple of guys who suggested the adapter/cables route, one showed us the Dinger digital to analog converter. Comments welcome.
