We have the Ferguson Ariva 100E Digibox. We've had it for less than a year and already sent it back to the supplier and had it replaced due to loss of channels.
Recently, we find ourselves with hardly any channels again, even losing CBS Reality, which we have never lost before.
We called the guy and he said it will cost us €20 plus transport to get the update done, we're not happy to pay this. Having done a bit of searching it seems that if I update the firmware and channel list it should fix my problem.

I know how to perform the update via USB but I don't know where to get the files from.

Can anybody help?
