I'm in the same market! I want a two-digital-tuner (watch one, record the other), HDD, DVDRW, VHS cassette device. Not found one yet.
The cottage has a TV, a DVD player, a VHS recorder, and a large stock of prerecorded VHS tapes and DVDs. We don't need a new TV, so one new thingybox is the answer - if anyone makes one.
