Ok, I think I found what's causing that youtubeid error. If I post any link that contains a hypen as the ID of the video, it'll spit that error out. If I post a video that doesn't contain such a character, it'll work fine. So, the link in my last comment would work as a test, or I have several others that would suffice as a good test ground. But each link that contained a hyphen would cause the error, and each link that had only letters and numbers would work fine.
