It's frustrating because I actually liked El Rey. Sure, the picture quality was lousy, and I was hoping that at some point an HD feed would be available (I think they're in HD on DirecTV), but as a sci-fi lover, I enjoyed the programming line-up, which mainly consisted of sci-fi programming that should be on the Syfy Channel, but isn't, because Syfy/NBC/Comcast are idiots who don't give two cents about what Syfy's core audience actually wants to watch.
El Rey was showing Stargate SG1 and Atlantis, Quantum Leap, the A-Team, Incredible Hulk, Xena Warrior Princess... in fact, in the past, they also used to show Knight Rider and the original V series as well. All of these are great shows, especially for sci-fi fanatics, and except for the A-Team which airs on Encore, none of them are airing on any other network right now.
In fact, I was actually in the middle of DVR'ing the episodes of Starhunter Redux, seeing that show for the very first time and really enjoying it too.
Hopefully the channel comes back at some point...
