Just bought an LG 42" TV, and I want to hook up a DirecTv DVR and DVD/VCR player to the new TV. The DirecTV receiver plays fine, but I cannot get the DVD/VCR player to work. The old TV (which was an old school tube TV) allowed me to simply press "Input" and I could go back and forth between watching the DVR and DVD/VCR. The new LG TV has many input options, but none of them seem to work for the DVD/VCR. I've had to physically plug the yellow/white/red cables from the TV into the corresponding unit (DVD/VCR or DVR) that I want to watch. Any help would be greatly appreciated!
