Finally completed digital switch-over in the Meridian region. (I live in Slough - long story but I pick up Hannington transmitter from my flat!). I now have the 4 HD channels - fantastic! However, I have noticed that when viewing them on my Humax HDR that the volume level does not work. I have to set the volume using the TV remote. This is strange but I have experienced the same when viewing mp4 files from usb drives and networked devices. Wondering if anyone is having the same issue? I am running the latest version of the custom firmware. Just to repeat that this is not a major issue but curious to find out if other people are having the same problem.
