As you may know Ive created a playlist of many of the dead videos on the sift. As its been there for awhile, and there have been quite a few views of it, very few vids have been fixed or discarded. I thought a list just of yours might be of some help. The list below are all your videos on my playlist. There may be a few errors, but I gave it my best shot.
