This adapter works great, but you need to get the setting right its not a magic adapter. It does what it is designed to do. If you connected it to your computer and you didnt change your resolution and it doesnt work, then it is working exactly as it is designed to work. Most (about 95%) of CRT TVs only have a resolution of 640x480. If you tried to connect your laptop or PC to a TV and you have the resolution set higher than 640x480, it probably wont work. Even with a HD TV, you cant get a RES higher than that via SVIDEO or Composite video cable.
