I'm suspecting Taquita & Kaui was canceled.
Here in the West Coast, the newest episode didn't air. I'm guessing the show didn't air either on the East Coast. Instead, they aired Adventures in Hollyhood, which IMO is a really boring show. Also, MTV doesn't play much reruns of the show. They air a lot of reruns of highly rated shows, so I guess Taquita & Kaui wasn't one of them.
