Hi Digital Fanatic,
From memory I'd say its approximately four to five weeks. Its not something that happens all the time, but usually when we find something good to watch
There are times that it will be fine for a week at a time, and then we'll have a bad evening. When I've checked the error logs at the point at which we have the problem I see a combination of either "Post-RS Error" or "No Signal".
Hope that helps?
Thanks for taking the time to respond.
Phil.
