I only have a Samsung HDD/DVD recorder but it doesnt upscale and upscaling hdd recorders are VERY expensive at the minute.
I saw the SVP Sumivision one which does 1080p but has mixed reviews.
I dont want to use my xbox as want to keep that for best. besides its connecting 2 things at once.
I saw a Panasonic 1080i upscaling dvd player at Sainsburys for £39.99 but as I say it only dos 1080i and not sure if it had HDMI.
