Here we go again. First it was NBC, and now ABC is tweaking the start and end times of some its biggest shows. Lost is ending between 9:01 and 9:03pm, which throws many DVRs into confusion with the popular 9pm show, The West Wing. ABC's Jeff Bader claims the 9:03pm ending was necessary because that week's episode of Alias -- which follows Lost -- ran short. By design, I'm sure.
