TVonics MFR-200:Tiny, and works on TVs without a SCART socket. Argos Online £38.99
Liteon LVW 5006 does it record from scart socket?
if so get yourself a cheap Technika freeview box from Tesco
Aerial to freeview box
scart cable to DVD recorder
you can set the timer in both machines
freeview box will switch to correct channel
and if you set DVD recorder to record from scart channel at same time.
I do this with both an old video recorder and AlBA analogue DVD recorder
