Over the past few months, I've watched as my Sky picture quality has degraded to the point of being almost unwatchable. The main channels are still good (BBC, etc), but all of the secondary channels suffer from major artifacting, pixel breakup, and very dodgy sound. Checking my stats on my Digibox, I'm getting a good rank for Signal Strength, but my Signal Quality fluctuates from roughly 40% down to 5%. (my estimates, based on the graphic) I've done a hard reset on the box, and since we've recently had some pointing done outside, I'm thinking that my Sky dish has been jostled or has started to loosen. Question is, how much does Sky charge these days for a callout? If it is something as simple as a dish realignment, would it be better for me to call an independent satellite guy?
