The Feesat box only has one tuner and only allows one channel to be viewed at a time.
If your daughter connects the scart from the freesat box to the video in of the HDD/DVD recorder and connects the scart out to the TV she should be able view or record the freesat channels. Connecting it this way should also allow her to watch a DVD whilst recording from the freesat box.
