A digital television receiver in the form of a set-top box includes a hard disk drive for storing a dynamic view buffer (34). Content from a live feed (40) is continuously stored in the buffer. The buffer can then be accessed at different points, thus allowing playback to be time-shifted. A cropping operation, whereby content is removed from the beginning (37) of the buffer is used to keep the size of the buffer in check. Cropped data can be used to create new record files.
