Edited sentence: An important feature of the EPG is its use in programming Freeview boxes that have built in digital storage to a hard-disk drive.Because it must be tied into the receiver, and because the storage capacity of disk drives is for ever increasing, EPG-based recording is best placed in a separate receiver box.In order to record a programme, the user has only to select it on a chart that lists channels down the screen, with a bar display of programmes aross the screen.It can be so easy to use that it arguably offsets the supposed extra complication that may put elderly people and 'technophobes' off buying a digital box.It follows logically from this that all televisions should ideally be sold as monitors only, for use with a PVR, which can then be updated as extra facilities or more memory capacity become the norm.It is particularly unfortunate therefore that 'integrated digital televisions' are being sold at all, which by their apparent simplicity are likely to attract those very people, since they do not usually incorporate this easy to use recording facility.No timer settings are involved, and with 'twin tuners' recording is completely separate from viewing, so that once a recording has been programmed or started it will continue unnaffected by 'channel hopping'.Regrettably, most sales staff in shops are unlikely to explain the brilliance of the EPG/PVR concept.Some units can even be set to start early and end late by a selected number of minutes to allow for delays in scheduling.Sometimes referred to as a PVRs, such units typically allow 10 to 50hrs of full quality (completely lossless) recording and playback.The incorporation of integrated receivers into large screen plasma and LCD televisions only wastes power, since any 'high-end' user is likely to own a PVR will not to want to go back to the primitive concept of a video recorder that needs timer settings.The marketing of separate [[hard-disk] or DVD-R based recorders that are not PVR's is also unfortunate, since they too need timer settings.This concept replaces, the video recorder, with a device that needs no timer settings
