I cannot change the screen format for any connected device. I do not want to just watch films in letterbox view only. All the Blu-ray commands work on the Sony handset and Panasonic handset except screen format on either. The s. format menuon the TV never works no matter what view you change it to. I cannot see that the Panasonic Blu-ray player is incompatable or has a fault as the sony handset works all its features exept screen format (aspect ratio on Panasonic). I realise I am not that knowledgable on technicalities so any help would be gratefully recieved.
