Battlestar Galactica was mastered in high definition, and had heaps of bonus content that was made by the producers at no cost to the studio. Universal and the Sci-Fi Channel (er, SyFy) have been extremely supportive of the series at all avenues. It's still on the air. Warner Bros., on the other hand, has Babylon 5. It's a show that wasn't mastered in HD, with effects that can only be completely redone if they must appear in HD format (all the CGI elements have been lost, only the few that were recreated for The Legend of the Rangers and The Lost Tales still exist). It's rarely been on television since it ended. And Warner Bros. (PTEN doesn't even exist anymore, and TNT stopped supporting it after 1 year) doesn't support the program with any kind of logical synergy (as recently explained by JMS).
