I want to hook a system
you will only be able to get digital surround( dolby digital ) from your dvd player( by the coax or optical digital connections ) , the rest will only be in virtual surround
from the dtv box plug the yellow video jack(RCA) into the vcr video input , then plug the audio jack or jacks into the audio input on the vcr. from the vcr hook the audio out to the audio in on the reciever( tv/vcr/sat... input ) , then also connect RF out from the VCR to RF in on the TV .
for the dvd player hook the "s-video out" to the "s-video in" on the tv , then the audio L and R on same s-video input , then send the audio out connection on tv to L and R input on reciever dvd L and R input , then you will need to connect the optical from the dvd player to the reciever or coax connections for the dolby digital on the reciever to work
