Re: Loss of HD picture on V+ box
 

Be sure that you are actually watching a HD broadcast. Not all show shown on the HD channels are truely in HD.
Look at channel 187, bbc hd as this is HD 24/7

You can check if a show is being broadcast in HD by pressing the info button 'i'. If in the synopsis it reads [HD] then you should see a better picture.

Also, as posted, check your connection. Pull out any scart leads to be sure you are not watching that.
Check that in your system settings menu / display and audio / that your setting read HDMI and 1080i.
