I agree with cymru the sound dipping is far worse this year.
As we all know the technology to just bleep out offending material and the leave the main body of sound intact is well established. E4 I think have chosen the cheapo option.
Also to do a bleep edit would probably take longer and they would not be able to classify it as a live transmission.
Given a choice I would not mind if it was delayed for an hour as long as what we watch can make some sort of sense.
As it stand at the moment the E4 coverage is barely worth bothering with as you only get to hear the boring bits for the most part.
