But it really isn't. Which is why DVD is still in play.
There's simply no content providers wanting DS9/VOY in HD, currently. I guess it could change? Though I think it becomes increasingly less likely the further we move away from those shows.
I don't agree. SyFy HD in the UK have currently got, and have had, TNG remastered on rinse and repeat since the Blu-rays went on sale. 2 episodes a night at primetime weeknights. I'm sure SyFy realises even the most die hard fans are thoroughly sick of it by now, but SyFy can't put poor SD upscaled on at 6pm-8pm weeknights on an HD channel. People will switch it off. I'm sure SyFy would love to have DS9/Voyager in HD.
