need answer

Question, When did InuYasha episodes go cgi? E-bay has a Sesshoumaru cel which the seller says is production, but it's from episode 134, the second part of "The Woman Who Loved Sesshoumaru" and I heard that InuYasha went cgi at either 100 or 101. I also read on one site that InuYasha went cgi at 90, which I know isn't true as I have cels from 96. So could some please clear this up for me?
Thanks!

hmm..bankotsu was cgi
