We tried all that was suggested...beer in cupboard brewing now...awaiting results.
We had to get Digiturk back (footie!)and the engineers said they fixed it. They moved the satellite dish, pressed buttons and thought it solved the problem.
They were on their way out of our house when all the channels they "got back" were lost again.
After much swearing and threats (not that much swearing really

)Phil just wants to see Chelski playing, 20 minutes later it was fixed...and has remained so...forever more I hope!
Anyway, it seemed like a common problem so if you have lost channels just get them in!
