Fix Fault Sagem

I have a Sagem Freeview HD Recorder where the remote is working but nothing is happening at the set top box end. Why?

I now find that during replay that my sagem freeview twin tuner recorder either freezes, sticks or stops, seems like a hard drive that you can't defrag !!!

When playing recorded programmes, the picture freezes and so have lost the opportunity to see the remainder of the programme. How do I correct this please?

The recorder is not working at all and the display shows err 07 or err 09
