I'm a DS9 fan myself, but didn't the repeats get cancelled on SPIKE a few years ago? DS9 doesn't do that well with general audience these days.
Maybe it's just that arc heavy shows just don't rerun very well compared to episodic shows like TNG.
I think that's true. You kind of don't get anything out of a show that runs in syndication where the episodes play out of order, but it's that very order that the series depends on for it to make any sense. Episodic shows do well because it doesn't matter nearly as much if the episodes are played out of order. Still, I think DS9 does okay.
