You're really picky aren't you? I mean, a bit of flicker is definitely there but to say that it's "unwatchable" is a little extreme -- to be honest, I don't even notice it that much when I watch it on my computer (I've never played it on any other computer nor on an actual DVD player so I don't know how it looks elsewhere).
But comments on the EDIT itself (instead of nitpicking on the quality of the video) would be much appreciated.
