There are plenty of freesat boxes, but only one freesat recorder that I can find.
Hi Duncan, there are three different Freesat models, and depending on which model you get, and your LNB, will allow how many TV programmes you can record while watching live TV, or not watching any live TV. Mine is the 500 GB one, and I can record two while watching one of them at the same time. A wide band LNB will give you more choice.

The box I have, gives me plenty of space to save and watch programmes many times, and it will only automatically delete the oldest programme first that has been saved, when the drive is full, if you programme it to record a new one. I believe the actual box’s all look the same, whichever one you get.
Regards Nick.
