I have a new Sony HD LCD projection TV hooked up to Cox HD cable box ( DCT6200) with video component cables, a Pansonic DVD recorder DMR-ES45V hooked to Cable box with HDMI connection and a Sony receiver hooked to the DVD recorder with optical cable for the surround sound. Everything is working except I cannot record on the DVD recordwe and watch another channel on the TV. I purchased a splitter, but I am not sure where to do the split. I do realize I cannot tape the HD channels. The Sony and Panasonic web sites have diagrams but they don't address my situation. Any help would be appreciated.
