How likely is it that one of the analog output channels on a 9 month old Hitachi DVD/VCR Combo Unit is malfunctioning? It is a model DV-PF73U. I completed the installation on my parents HTIB yesterday and everything checked out except the Right Analog DVD/VCR channel connected to the Receiver. The best I could get was about 20% volume. It was not a cabling problem because I swapped cables just to make sure. Or how likely is it that the Right Analog VCR input on the Receiver is not functioning? I did not think to try one of the auxiliary inputs on the Receiver to verify that theory. I will definitely try that. Thanks.
