Page 1 of Wharfedale DVDRHD400F DVD Recorder with Freeview/80Gb HDD

Hi,I have just bought the above dvd recorder and is all connected and working ok recording from the built in freeview and my external sky box via the scart input.The problem I have is that I want to record some of my old videos onto dvd format.These are old films recorded from the tv and family dvds etc and are as such not copy protected.When I try to connect the vcr I get sound but no picture.I have recorded to dvd but only sound.I have left the scart from the new dvd recorder(output) to my tv in place and removed the input which comes from the sky box and replaced it with the feed from the vcr.I have also removed this lead to test and put it straight into the tv and the vcr works ok.I am positive the connections are right,should it be possible to do what I am trying to do.Do I need to amend any of the settings ????
Any help appreciated.
thanks
Gary
