Yes, i have this pblm also. Some shows are off by 1/2 second, but some i have tried to watch are off by as much as 2 seconds (which makes them unwatchable IMHO). The strange thing is if i unplug the VOOM STB for 5 minutes and then plug it back in, one time this fixed the sync problem, and other times it seemed to change it from 2 seconds to 1/2 second, so this may be a VOOM pblm as well.
