I have a Pioneer VSX D912 receiver that I recently bought. I just found out that I can't get my vcr video to work. I plugged the vcr into the vcr video/audio jacks in the back and got sound only. I then plugged the vcr into the front aux jacks, again only got sound. I then plugged a portable dvd player into the front jacks, again audio only. Are my 2 video jacks bad? (which would be a strange coincidencee) or is there some type of setting I'm missing. I'm very confused. Thanks for any help
