You may wish to review your last statement. We have had BT Sport 1 and 2 added 
just recently (this week). Hasn't affected my myth installation that I know of - 
though I know I'll have to spend a morning re-scanning - but it completely blew 
away the TV. I had to reset to factory settings and that has blown away all my 
myth customisations :(
