I have a JVC sa75gd DVD player with a DD and DTS decoder chip in it. When i play a DTS track I get a chirping in the back right speaker. Its a fairly high pitched noise. If I switch to DD its fine. Has anyone ever heard of anything like this happening? I was also thinking that it may be my receiver? But it uses the same 5.1 inputs, so that kinda doesnt make sense? I have checked all conections, they are fine... as it plays A ok with DD. hmmmmm?
