I'm sorry to hear that some of your recordings have disappeared. Have you looked in the 'Deleted Folder'? It's worth having a look in there to see if they are there. If not sadly they aren't recoverable.
I wanted to pop our On Demand guide here and hopefully some of the programmes you were watching are listed there for you. If so then hopefully all is not lost and you can watch them via On Demand as a way around it. I know it is not the ideal solution, but thought would put it forward in case it is useful for you.
If you have any further queries, please don't hesitate to ask.
