RDD: You could do what I've done, and have for some years - split the feeds from the wall. I originally did it when it turned out that my PVR was much more sensitive than the freeview box, after getting a new aerial.

One of the reps at work (who'd formerly been a TV installer) kindly made up a set for me, but its easy enough yourself.A decent bit of coax out of the wall socket, then a good quality splitter, then two cables off that, one to the PVR and one to the TV. Mine has F-fittings, but whatever works.

Then you can vary the attenuation seperately, and looping through isn't an issue. I got a variable one, but it didn't seem to do much, so I got some from Amazon (the same as these https://www.maplin.co.uk/…59p) which fit into one another, so you can buy perhaps a 3db, a 5db and so on, and put them in series to get the right level.

The trouble with a masthead amp is that you can't just switch it off (my new house has one), but at least you can dampen it down.

MikeB:
Thanks for the suggestion. My concern is that splitting at the wall will lower the signal to the DVR which is already at circa 55% . However this could be due to the tuners of the DVR being less sensitive than the tuner of the HDTV..

However, I will give it a try and see what happens, I think I have enough bits a pieces to rig your suggestion up.
I will let you know. Thanks.

XIAO: Have you checked for any loose or damaged cables or connections behind your TV and set top box?
