I have followed the above tutorial and applied a HDR. It shows up in the Material room but no matter what I do I cannot get of the  beach scene! What am I doing wrong? Cheers

It is difficult to say from here. I think you may not have used the 'scene' option in the 'Replace all identical', or you had already changed maps before. 

The environment map is used in the environment preview, in the background (used during render), and in the single light used in the  preview. The 'change all identical in scene' works only in all three locations when the maps in these three locations are identical.
