TAS - DVD
DS9 - all seasons, DVD
All movies - I-XI: DVD (2 disk editions)
(Also have movies I-IX on VHS!)
I'll probably get TOS on BD at some point, but I'm not in a hurry as I have such a backlog of DVDs and BDs to watch. I'd probably pick up TNG on DVD if it gets down to a price mark of about $20 per season. No interest in VOY or ENT.
