SG-1 Marathon on SyFy right now!
Prometheus Unbound is rerunning this hour on the SyFy channel now. Threads is up next then Moebius 1 & 2, then I think 200 and Unending. It seems like they're doing a "Best of" marathon. I caught Window of Opportunity this afternoon, then Wormhole Extreme, Abyss, Heroes, and Lost City.
