Sony DVP-NS70H HDMI Single Disc DVD Player
Sony DVP-NS70H upsampling HDMI DVD player
I have tested the DVP-NS70H (with an HDMI cable and upsampling to 720p) against a Sony DVP-NS575P DVD player (with a component video cable and 480p), using a Sony Bravia KDL-V40XBR1 LCD TV to examine the results.  A good-quality DVD movie appears to have more vivid color and less noise with the DVP-NS70H than with the DVP-NS575P.  A lower-quality DVD, such as an annual release of a TV series, does not demonstrate the differences between the two DVD players. <br /> <br />I do not know whether the HDMI cable or the upsampling is responsible for the improvement, but I suspect that HDMI may contribute to the improvement because HDMI bypasses the TV's A/D convertors.  If you purchase the DVP-NS70H for an HDMI-compatible TV, do yourself a favor and buy an HDMI cable from Amazon for less than $20, which is a lot less than the $80 to $100 that you will pay at your favorite electronics retailer. <br /> <br />I am very pleased with this product.
