I have connected a pioneer dvr 433 recorder to my system following the diagram. I have a 32" sony widescreen TV, a sony VCR and the pioneer recorder. I now find that I cannot play or record on my VCR unless the pioneer is switched off. On page 16 of instructions it clearly states that watching or recording on VCR is possible while recording on the dvd recorder. My last system was able to perform this task.
