I mentioned this in another thread but I think it's important enough to deserve it's own thread and I know many others over the years have been asking for this:
Give us ability to automatically search for Season & Series Premieres.
Would be even better to allow wishlists for the above, but at least from HD Search give us ability to search using above categories.
This capability has been asked by many for years but never seems to make it into the various Tivo search capabilities. DirecTivo & ReplayTV have this functionality so I don't see why Tivo can't.
