i believe so..you are saying like hook 2nd dvd player audio up to CD or MD/Tape option? i could do that, but i would like to hook 2nd dvd player up via optical digital audio rather than composite and that only inputs to dvd/ld. couldn't i use that as well as the 1st DVDp hooked up via coax digital as long as 1st player is off when 2nd player is on?
