How to play recordings when Recorded Program list lost?

Following advice from another thread (which was received enthusiastically by dozens of other people with the same problem) I reset my Humax PVR9200T to the Default Settings.

According to the Humax manual all data, such as the Channel List and User Configured Data, will be deleted but no information on the HDD wiill be lost. This is true, there are still around 60 GB of recordings on the HDD but how on earth can I access them when the Recorded Program Play List is empty and nothing shows up in Menu > Recorded Programme?

Any solutions will be hugely appreciated.
