Thanks, will look into this a bit more. The Humax I have has always had lip sync issues in HD with my LG TV with Humax blaming LG and LG blaming Humax, hence the reason I thought it would be good to get it all built in.
Some TVs have an input lag as they upscale to the resolution of the screen, and some TVs are worse than others.
I have just bought a humax DTR-T2000 and I think I saw that it had an Audio delay configuration.
However the required audio delay can change depending on the amount of upscaling the TV has to do.
I found that the best bet to avoid sync issues is to take the audio feed for the stereo from the TV itself (many have an optical out), and not from the PVR/DVD player.
