Just bought one of these myself, and although I cannot answer any of the original posters questions, I do have some general comments on the unit.
for Â£350, it's a great bit of kit, with ample space on the HDD (160GB), and the capability of writing stuff out from HDD to DVDR(w) (+or-)
Pro's: loads of space, menus are a breeze to use, with some very handy wizards for doing common tasks.
Cons: Remote control is very cheap quality, and a real let down, for the sake of a few Â£Â£ more manufacturing costs. Does not play or record MPEG4 (XVid/DivX)
