I think a lot of people upgrading from a VCR set up to a PVR set up don't always understand or realise the capabilities of the hdd. Some are big enough to act as a small 'archive' in itself and are more convenient than storing stuff onto DVDs.
I think because we were so used to putting stuff onto physical, portable VHS tapes for so long but it is no longer necessary these days, rather like not having the need for hard prints of photographs any more.
I know someone who has a PVR but
STILL only uses it as a secondary recording device like a VCR rather than have it as their main viewing/recording source. They would rather use the TV's built in freeview instead
