In my case, I first noticed this phenomenon while watching CSI live OTA via TiVo, connected to my Mits RPTV via component cables. The next day I played back that particular segment of the show though another of my TiVo's (over my network) connected to a 46" LCD in the bedroom via HDMI. Both TV's displayed the same blue cast in the same manner. I don't believe my cables were at fault. YMMV.
