Thanks techo for your reply. Perhaps the problem lies with being connected to too many units? ie PVR, Pioneer DVD-R with HD and analogue tuner, hi-fi midi system, VCR and LCD TV. I've tried different order in daisy chain, restoring to factory settings, switching off at back, each time scanning the channels. The result, schedule program plays back bitty and jumpy, and when I switch off at remote, so does the recording end. The "Purpose" still displays as PLAY and No Repond. I'll give up for now and record my programs through the analogue tuner of the DVD-R (very reliable and eeeeasy to use!)
