If by "his TV is digital" you mean it has built in Freeview, then two Scarts are not necessary provided the STB has RF loop through. In this case the aerial will be connected to the STB and its RF Out connected to RF In on the TV.
Also, if he does not need to record one programme and view another concurrently, it may be possible to record from the TV onto VHS, obviating the need foa a STB. For this the TV would need a Scart with video out.
I imagine that scheduled recording will be less straightforward because the time/date information is no longer available automatically, necessitating manual set up of these. This needs to be done after every time power is switched off to the VHS for more than a given time.
I realise that this might not be the answer you are looking for, but wouldn't it be easier for your friend to buy a Twin Tuner Freeview Personal Video Recorder (PVR) with a built in hard drive (300Gig+ recommended) and use it to make the recordings, two at a time if needed, that he wants.
The VHS recorder can still be used to playback tape recordings already made and can also be used to make recordings onto VHS tape if there is still a need to do so.
I have not had the expeience of analogue switch-off yet but I do not expect there to be any point in connecting an aerial to a VHS Recorder since after that event there will be no analogue teletext. Are you able to confirm that I am incorrect?
Yes, the Humax HDR Fox T2 would be just what the doctor ordered, but if your friend has deep pockets and short arms I don't see him getting one - unless, of course, you want to let him have your one ;->
Erm... I may be showing my ignorance here, but surely there's no way an analog VCR can record digital transmissions? If you've got a bunch of ones and zeroes coming down the pipe, surely an analog VCR can't record them or play them back? I'd have said a PVR is the only way to go. Happy to stand corrected, though.
