That what I though and I am glad it that and not my tv As the tv is very good as I am one of the lucky ones that got one that dont buzz

Just was hoping it a common thing and not a funny tv as I did not fancy changing it incase the next one buzz LOL
I believe different programs are compress differently different time. Ie I watch ready steady cook Yeah sad aint I lol but one day it pretty good the next day it rubbish so they must compress differently each time
