ABC is airing Grey's Anatomy from 9 to 10:15 then showing a 45 minute Lost "Recap of Secrets" till 11. CTV is showing Lost from 7 to 7:45, then Grey's at 7:45 till 9 followed by CSI's season finale. Looks like no repeat airing of Grey's on Friday.
I realize this is all part of the competitive approach between the networks but in reality it must be anoying to a lot of viewers. Starting on the hour and ending on the half-hour or the hour has worked very well since day one of North American television......lets just leave it that way!
