Alex: Nonsense. If the BeoVision works fine for gordongofer at the moment, then there's absolutely no reason to update the software.
The TV will need to be connected by HDMI and Scart. The Scart will supply the image to be piped round the house. Set the Sky box to 1080 - the BBC have now started broadcasting in 1080p which is a big step up from the 1080i we had before...
According to the thread regarding the 4.24 error, especially the Sky Boxes are causing problems, but as you say, since he is not using 4.24 then the crash to off error will not exist, however there could be some problems regarding on/off sync off the Sky HD box with earlier versions that 5.02.
BUT, if i had SW 3. something then i would always get the latest SW. 3.someting is old.
Gordongofer : try to connect your Sky box, and if you are experiencing funny things, then get the tv updated to 5.02.
