This is a weird one - I've just installed a Sony digibox to replace my aging and unreliable Amstrad. I know the optical out only supports Pro-logic, but I figures it was still better than the analogues, so connected it up. The sound is fine, but is about 2.5 seconds ahead of the picture I've forced a new s/w download, tried other optical leads and swapped inputs on the amp (not that any of this could logically make a difference), but it's still ahead of the picture, even when viewed via TiVo, which adds just under 1 second delay. The cynic in me would accuse Sky of deliberately screwing up the optical out, but I doubt even they would go this low, and if they did, they'd probably just turn it off altogether. Any ideas? The analogue output is fine.
