I've just acquired a Pio DVR545 hard disk DVD recorder and rather than faff around trying to get the connections right (maybe!) I thought I'd pick a few brains here and save myself some grief. So here goes. DVD manual states that a VCR should be incorporated as the first item in the set up so ............. VCR in From outside aerial VCR out to DVD Digital In DVD Digital In From VCR Digital Out Loop to DVD RF In RF In Loop from Digital Out RF Out To 436 Monitor Box Monitor Box Ant Digital In From DVD RF Out Finally DVD HDMI to Monitor Box HDMI Input 4. Hopefully that's it but all advice gratefully accepted esp by SWMBO who doesn't appreciate my vocab on these sort of occasions when things don't go quite as planned!
