I bought a Philips DVP5990 and hooked it up to my 1080p Sony via
HDMI hoping to see some wonderful 1080p pictures from normal DVDs. Well I was very disappointed. First, the picture quality was probably worse. Based on what I read above, I suspect the chipset in the Sony TV is better that what is in the very low cost Philips. However, the real flaw in this plan is that the DVP5990 provided distorted pictures to my TV and I had no way to control the output from the DVP. With my older Sony DVD player I would get whatever was native to the CD and control the zoom with the TV itself, resulting in much better pictures. While some higher end upconverting DVD players may do a better job with improved functionality and controls, I was disappointed in these results. The new Philips upconverting player is disconnected in favor of my older Sony standard DVD player. My next purchase will be a Blu-Ray player so I can get a real 1080p source.
