vocaloids

I want to download Vocaloids from the Zune Marketplace but when ever I search the names they do not pop up. Are there other names for the vocaloids?

I've been looking all over the place to watch these episodes, but I can never find a good site that has good quality and all the episodes. I've already tried YouTube. :(

well ive seen: Kaito, Miku, and Len. i wann c Rin's but everytime i search on youtube i give up cause all da videos that arent it. now im thinking she doesnt have one. if there is one, can someone give me a link with english subs. ill take it even if it doesnt have them, but id prefer subs.
