My Mom's old RCA tv has separate composite and s-video in jacks, but only 1 set of L-R audio inputs. She just has her dvd and vcr play through the tv speakers; the vcr is currently using ch 3 to play so there is no problem with sound. I want to keep things simple for her and hook the vcr up with video in. Is it ok to get a couple y-connectors and hook the vcr and dvd audio outs to the same input on the tv with the y's? Of course, only one item would be ever playing at a time. What would happen though, if both the dvd and vcr were on at the same time? Would the sound just be garbled or could any damamge occur?
