I've don't have $ky and a 1-second delay is a small price to pay so as not to
have to get it. I associate your intolerance with young male gamers

which probably means you're Mrs Ponsonby-Fanshawe of the Midsomer WI.
Although each model PVR has certain characteristics and performance standards, they can vary from unit to unit. My slowest PVR is the Tiscali+ but it's got an excuse, in that its signal comes down the phone line. My "good" Vestel is not far from instant but my "bad" Vestel... the less said the better. The Topfield takes a slow blink. I think it's to do with signal reception and decoding, but have no expertise.
I suppose of one is using $ky
and a Freeview PVR any delay on the latter could be irksome, but if one only has a Freeview PVR then one soon gets used to it and it's not an issue.
