I posted this on the Plasma forum so I thought I might ask here as well. I don't really know if this is a big deal or not. I have a Panasonic TH-50PX60U hooked up to a Toshiba HD-XA2 HD DVD player. The player is currently outputting 1080p to my set. I was looking through the settings menu and I see that the color matrix is set to SD, puzzled by this I changed the resolution to 1080i and then 720p. With those signals the TV was using the HD color matrix but with 1080p it uses the SD color matrix. Anyone have any idea what it could be? Thanks!
