I'm not saying that's OK, but it is a lot less disturbing than sound before vision.The video is ahead of sound. If you watch a news broadcaster the lips start moving before the corresponding sound starts.
Correct, on the assumption that video takes longer to process than audio (plus the physiological effects as noted).The sync adjustment on the Humax caters only for sound ahead.
Then they are idiots. The error is in the processing.LG said TV HDMI's were faulty and replaced set but same thing happens.
Yes, exactly my thoughts - it sems such a basic thing. Often wondered why film makers used a clapper board but it sycs the sound to vision. No reason why this shouldn't happen electronically with all programme output. Even if I could get my kit in sync I would have to change it every time I changed from Humax to TV's tuner or one of the installed apps and this is just not acceptable.I'm not saying that's OK, but it is a lot less disturbing than sound before vision.

The industry missed a trick by not embedding sync information in the data streams so that everything can be matched up at the presentation device, regardless of the transmission chain.
renzz, thanks for that. Do you know what the increments are in terms of milliseconds? I'll give it a try.What about trying the boot-settings package which allows you to manually configure the Lip Sync setting - https://hummy.tv/forum/threads/boot-settings-apply-settings-during-boot.7678/. Although this seems to have a slider from 0 to 100, it does seem that you can manually type in a negative number but I haven't tested if it actually works. Worth a try....
BTW, multi channel sound on Freeview HD is in the AAC-LC format. Given very few (if any) AV amps or TVs can handle AAC sound directly, Freeview boxes will re-encode it to Dolby Digital to make it more compatible. So it could be that the delay you are seeing is due to that process, but I've never experienced it on either of mine - the resultant DD audio is always perfectly in sync.
