This is MTBdude's TrustRating, which is based on both the number of reviews MTBdude has written, and how many other people have voted those reviews as "helpful." It's a way to quickly to determine the value of any single review or reviewer, because it's based on how helpful MTBdude has been to the Kudzu community.
I would have rated this higher if I supplied these guys with higher quality video. They did great work with what they were given - memories on VERY old tape. It's all on DVD now and we can watch them anywhere!
