Does anyone know why there is a lip-sync issue with my Humax Foxsat PVR - but only appears to affect the Countdown programme on Ch4?

I've tried changing channels, but that doesn't rectify it.

Yes, I'm sure you are not alone. I also have had lots of progs out of sync to varying degrees, inc. Countdown. I assume it is a broadcast fault and not a Humax fault.

I'm still getting lip sync problems with Countdown. Apart from "Alsation", are we alone in this?
