TV Repeats Schedule?

I’m having a hard time finding out when repeats begin for “Lie to Me” and some other shows. In this case, episodes are available from the website, but only recent ones, not the first few that I missed. And because repeats don’t always run in the original timeslot, I can’t count on my dvr to record them.

Is there somewhere I can find a listing of shows and the dates that repeats will begin?

IMDB does this, but it’s only going to go out so far. It depends on how far in advance the network actually determines which episode is going to appear when. I doubt they do this more than a few weeks in advance.

Where do I look for that? I’m not finding such info.
