[QUOTE="PaulR, post: 23895, member: 176256"] I reckon that it's a function of digital TV in general. Both sound and video are run through what is essentially a computer to compress them. The sound requires less treatment than video so remains nearly unaltered (in time) compared to an untreated signal. The video, however, requires a great deal of heavy-duty processing and this shows up as the video lagging slightly behind the sound. You don't even have to have a digital receiver to notice this. As all the processing takes place at the broadcaster's end this artifact is noticeable even on analogue TVs as somewhere along the line the signal will have been digitised. Try watching the live news on an analogue signal - you'll see what I mean. PaulR Things might get better in the future as faster signal processors become available so the delay might disappear some day. [/QUOTE]
