ok, thanks, I knew I had played with a menu to output but couldn't remember if that was the old V+ box, or my current tivo box
on TVs with freeview, with 2 scarts, at least one is bidirectional, I can record to my panasonic DVD-R/HD recorder freeview programmes from my tv via scart (the recorder is pre freeview) but that could be a special case that they just output the tuner, rather than what is being watched.
if/when I get it working i'll post what I did, 'cos someone else is bound to need to do it
