Thank you everyone, I may email Taro about this.
And I would just say, Kenshinlver, that as I 
stated before, I WOULD have checked before buying-
 but in a situation like that you really don't 
have time to. I saw it early in the morning- and 
by the time I got home from work that night and 
popped a tape in the VCR the cel would probably 
have been long gone. (However, I think it IS a 
lesson to do so anyway and check next time so 
that if there's an error, I can do something 
BEFORE it gets mailed to me.) And the cel looked 
familiar to me- in fact the sequence it's from is 
very much like the sequences in the OVA 
beginnings. So I guess it's an understandable 
error on both mine and Taro's parts.
