As reported neodigits started to ship the Helios H4000 upscaling DVD player (up to 1080p) about two weeks ago. The company was kind enough to send me this DVD player for review:

Quote from the review:
"So you have a HDTV, but nothing to connect the HDMI port to? How about getting an upscaling DVD player that uses all available lines on your fine HDTV. Most upscaling DVD players do 720p. The neodigits Helios H4000 is even able to upscale to full high definition resolution (1080p).
I had some doubts about the benefits of upscaling before reviewing the H4000. I was pleasantly surprised that it really makes a difference. "
