Kind of off topic, well, totally off topic... Laserdiscs suck. I dropped Terminator 2 taking it out of the player and it shattered like glass when I was a kid. My dad almost beat me cause the thing cost 50 bucks. Stupid lame formats. We had 3 laserdisc movies...T2, Robocop(my personal favorite) and Total Recall.
Just some random facts for ya. 
Little of that was fact, just that you dropped a laserdisc and you're blaming the whole format for your negative childhood experience.

But I happen to still like Laserdiscs even in the age of DVD considering there's still a good amount of material (deleted scenes and entire movies) that haven't made the jump to DVD. Though it's more of a curiosity I keep around now rather than for home theater watching.
Anyway, the DVD and CEDs are two different beasts. The CED was pretty cool (or awkward) in that you slid in the entire case, pulled it out and it plays.... somewhat poorly depending on how many times the disc was played. I always liked the little "space-age" RCA jingle that played (it's on YouTube for the curious) and the general idea of it. They're still floating around so I may pick one up if I ever see it (though it almost certainly will be in disrepair).
