I have an Sony CRT RPTV (KP-57WS520). I've tried three different upscaling DVD players....Sony 975, Sony 70, and Toshiba 592. While upconverting to 1080i with the 975, I experienced severe green depression. The other two players produced severe red push, but no problems with green. No color issues with these players at 480p (with or without HDMI). I've thought about trying another upconverting player again (maybe Pioneer 59 or 79AVi). However, is it likely I will enounter color issues again (color space issue)? Is my TV just not color compatiable with SD upconverting? Or, is it just the DVD players I've been using? In the meantime, I've just been sticking with my Panasonic XP-30 using component.
