Are you saying the reruns have generic guide data? If so, that's how the Tivo has always worked -- record them IN CASE they are new. That's the only safe thing to do, even though in the real world, the vast majority of time those are reruns. (another example I'm hitting lately is Cops.. since Spike or whichever station it's on now doesn't give guide data to all of the reruns.) You can use hacky autorecording wishlists if you reallyreally want to try to outsmart it.
