I just replaced my old Sony DVD with a new Toshiba VR4 VCR/DVD recorder. I have connected the DVR to my TEAC Home Theater Receiver. Everything is working; however, the sound coming through the receiver is much lower than if it was through the TV. I also have to use the TV sound controls to adjust the volume wich I did not need to do with my old DVD player. Any thoughts on how to correct? Thanks.
