I am trying to loop a DVD player through the Humax pvr but the Humax overides the DVD when turned on and cuts the signal when turned off. Any ideas what I'm doing wrong?

Just a guess turn the power saving in standby to off

Thanks. I had no problem with a standard box. So that may have been set thus. I'll try your idea

And press source on the remote when it's on. To work you have to have a scart connection to the TV in addition to the hdmi.

Thanks all working now
