LG Dr-7800

I’m struggling to find a fairly cheap recorder that

  • has RGB in, out & passthrough
  • has firewire in
  • (ideally) dual layer.

I used to have a technika dvr2005 (a Yamada 8400x clone) which did this except dual layer, but failed after 3 months (loader looked poor quality)

Best current candidate is LG DR-7800 (80 UKP) but I can find no online manual or confirmation it has RGB in. In fact RGB is a problem for many dvd recorders. I’ve bought several Liteons after being assured they had rgb in, when they didn’t… I think only the 5006 does…
So does anyone know if DR7800 has RGB in?
