Id look at something like the archos tv plus, wifi a must these days with a media player, then you never have to worry about disk. share your PCs media folder upstairs with the archos, and you never have to worry about the disk under the telly again.

the archos is a PVR as well.
before anyone else posts, yes luzerntech are what they are, they sell refurbished kit. Youre taking a chance buying it, if the kit dont work, theyll only refund the kit not the delivery, but the prices are great if you like shiny stuff.
