I find it changes (sometimes within a staion - one program fine, next has about 15% chopped off wach side)
In regard to being out of synch (it's really annoying!!) I find the best is to pause for a moment & play again, you sometime have to do this a couple of times.
Also, sometime it freezes - anyone know is there a way to reset it other than unplugging the set-top?
I know these are slightly annoying, but I reckon the benefit of pausing, rewinding, recording etc., at a cost of just €5 extra per month is worth it. For me to get the programs I would like with Sky would have cost alot more than this per month.
