Review by Rich : VIdeo out for Samsung Captivate (Galaxy S)

Simply plugged this in to my Samsung Captivate, enabled video out, and I had picture/sound from my phone on my tv. Not much more to say, worked as expected.As others have said, I had to swap the red and yellow cables, so red for video and yellow for a sound channel. I don't think this is the cable's fault, I imagine Samsung didn't follow the standard for this cable type.

Review by Mark Winfrey : Device-dependant advisory

The cable I received does not look like the one in the picture, it has seemingly-superior connectors with metallic plating, so I imagine they manufacture these things as they need them and will vary slightly. It's a cable, so there's not a lot to get wrong and it works fine, with one slight comment that needs to be made EXTREMELY clear.If you plan to use this cable with certain devices, the colors have to be swapped around. This is so ridiculously unintuitive that it borders on criminal. Certain devices want you to buy their "special" cables so they swap the colors around but it is essentially the exact same as the standard RCA cable long-used for video cameras. My device used the same swapped order as the iPod (red into yellow, yellow into white, red into white). I used a colored band of electrical tape on each to remind myself which one goes in which.Save the $10 difference between a standard and "special" cable, tell your friends, and hope that enough angry people will convince them to stop making deceptive products like that.
