Thanks for replying Wibble.
In a non-technical sense: My old Wega was permanently set to 'smart' which meant that if I was watching Sky News for example, the picture would be stretched to fill the screen, losing some information in the process.
If I then switched to BBC News 24 which broadcasts widescreen, the TV picture would automatically switch to widescreen, and back again if I reverted to Sky News.
My KV36FS76 (which has now gone tits-up - see
http://www.avforums.com/forums/regis...968&i=63918901) didn't want to do this when set on smart.
The picture output settings on the digibox weren't changed when the new TV arrived by the way.
The picture was fantastic by the way - While it lasted
