I've recently compared the Sony 775 and 975 DVD Players using component 480P. Closely doing A/B comparisons with several different movies, the video quality appears to be identical. Using Avia, I put in the Zone Plate test --- again, everything identical. However, using Avia's YC Delay pattern, the 975 player is at 0; the 775 player is around +.07. Is this significant and what does it mean? I do understand component cable length can alter this, however, the cables are about the same length for each player. I've been doing searches on this forum and on the internet and can't find much out about YC Delay as it relates to DVD players. Avia does give a brief tehcnical description of it. But, I was wanting to know more about the practical/viewing implications of it.
