W O T ?    no one else getting this issue ?

Colin can you tell us what box you are using re your TV service if it's a humax box try this ... If not let us know your sat box details.
To narrow down the problem you could try using a scart connection rather than the HDMI, if your TV has a scart input. If the scart works O.K. it maybe worth trying the different video modes using the Remote Control V-Format button
