And the whole point is that you buy a blu-ray player, and then buy more blu-rays. It's the same as how they didn't release the remastered DVDs on VHS again. Well actually they kind of did in the UK, but only for three or four seasons...
Wow, REALLY? They rereleased it on VHS? Talk about a waste of time and money!
Yep, seasons 1-5 were re-released on 3-or-4-episode tapes between 1998 - 2002. In fairness, when they began in 1998, DVD was only JUST coming onto the market, and was really really expensive. I suspect a lot of VHS manufacturers (whatever happened to CIC anyway?) hoped it would go the way of laserdisc.
Of course, by 2002, the writing was on the wall, hence why TNG season 6-7 was never re-released, and Enterprise only got season 1 released on video.
