I think they only released a few episodes of it on whatever that DVD release was.
I'm actually thinking about getting the damned set. I don't remember much about the series other than it had a kinda cool premise but was not well executed, and definitely diverged away from what was in SG-1. Although that can be forgiven a bit since a lot of the mythos, especially about who or what the Ancients were hadn't been establish at the time. Oh but did it have an abhorrent theme song.
It's definitely at the bottom of my list though. Last to buy. Probably if it goes on sale or clearance or something.
