What we're watching: Heroes and 24 have been battling for our attention for months now, and it is no different now that each has its season finale on the same night. We won't forget about Game 1 of the NBA Eastern Conference Finals between the Cavs and Pistons on TNT, or the season finale of Law & Order: CI, either, but two hours of Jack Bauer is tough to turn down.

Our traditional high-def listings continue below.
