We've had some trouble with video signal pauses with our SkyTV connection. We've had it on three separate days. Strangely, not all channels had the pauses. In particular, free to air NZ channels didn't have the pauses.
So it wasn't the signal transmission from the SkyTV satellite to our rooftop satellite dish. I thought maybe it was some issue with how Sky was pushing the data up to their satellite, from wherever it was coming from (UK and U.S., mostly, I think). That didn't seem right though, since there'd be a major public relations problem if all non-NZ video feeds had pauses.
I still don't know what the problem is. Today though, I applied Windows solution #4: Reboot. It wasn't sufficient to just turn off the decoder settop box. I had to unplug it and plug it back in. That seems to have fixed the pauses though. I guess there's some sort of problem with the decoder starting up sometimes, when we turn it on in the morning, and power-cycling it fixes the sync problem.
I'm very glad about this. My mother-in-law and sol really enjoy the Food channel (we spend the great majority of our TV watching time watching cooking shows there) and sometimes we all get frustrated because a particularly good show with mouth watering food is unwatchable because of 3 second pauses every 3 seconds.
I hope this problem is consistently solved by Windows solution #4 :-).
