hard disk recorder for fta sat channels?

hi,
just came across this forum, looks good, sorry if this question has been asked, or, if its a really silly question.

we live in france and have a sat dish and digi decoder for the free to air channels picked up on the sat dish.  is there a hard disk recorder out there that will work? like the sky+ service.  I see the hard disk recorders available for freeview (uk freeview digital channels) but nothing says they will work on free to air sat channels (although the source is all digital).

are they available? also, would they work so you can watch one channel and record another.

many thanks in advance
Darren
