what is Haibane Renmei episode 0 ?

I just saw Haibane Renmei 'episode 0' posted to a.b.a - is it worth getting? If I understand the cryptic lettering right it appears to be subtitled in French.

That's something to do with the more recent versions of xvid. You should probably upgrade your xvid codec, and maybe try the player that comes with DivX 5. I also see smearing (and worse) if I play Wizzu subs of episodes 5-7 in WiMP, but those aren't xvids, so they managed to screw it up some other way.

Anyhow, it seems to be clips mostly from episodes 1 and 2, but has bits from as far along as episode 6. But nothing that's not shown in the series itself.
