Thanks ramjet, but I have the recorder set to digital and by repeatedly pressing the input button on the remote I'm given the options of Line 1, Line 2 or whatever programme number the recorder happens to be set on. No mention of DTV.
Rob, yes it's set to Guide(digital.)
Just to reiterate, I can do the initial setup without a hitch, programme guide et al, but as soon as I switch off and back on, the guide has been deleted.
Your suggestions are much appreciated btw.
the question is , did you use the centre mounted rear aerial sockets which are the digital input and output sockets ?
if you have and you have scanned in the freeview channels , then those channels are DTV and you will also get L1 and L2 when you cycle through them using that input button , and you wont get PR but D001 to D005 for the normal channels , where D is for Digital
when you are on freeview bbc1 (D001), or itv2 or whatever, press guide, and as long as you have set the box for the digital epg like rob said (and not the default which is the defunct guideplus) then you will get the 7 day epg menu populating
as long as your firmware is up to date then it should work properly and survive a switch off
I would start again with a factory reset as outlined in your manual, and also scan with the aerial out to clear all the slots too
then plug the aerial back in and do a digital channel scan and ensure you get freeview, also check the time is set correctly, and ensure you have digital epg set for the guide
then place the box on the freeview channels, say itv2 just to be sure, press guide and the digital epg guide should show
the point here is that if you are on L1 or L2 or the old analogue PR channels then you will get the error message you are experiencing, it seems to me that when you power up its on the old analogue PR channels or its on L1 or L2 causing the failure you mention
ideally you want to select digital channels (freeview) and then switch off overnight, and so when you power it back up again the day after it should power up onto freeview channels and not PR or L1 or L2 as that will result in black screen and your error message
