I bought this thing, it works fine. Sometimes the video will look distorted at first, but you just have to play with it for a few seconds untill it snaps out of it. Another downside: When you are playing it and you want to fast forward or rewind, the screen goes black, so if you're just searching for a specific moment you have to keep hitting play to see if you've passed it what.
long linkI'm sure theres better devices out there, but this is an easy-to-find, relatively cheap one. I found this one at my local Best Buy.
