Perhaps that was the issue. I too can see similiarities between Dean and Seachange
Anyways, I am happy to report that in DA1 at least I have what appears to be the full backlog of Demand5 catch-up for the last week.
I can't be sure when it started working again, (obviously some time after Friday night), but it all seems to be there!
Still bitterly disappointed with Virgin's lacklustre response, but then again why would they care about keeping customers happy. It's not as if there is any other way to get TV, Broadband or Catch-up TV services.... ;-)
