    Hey guys,

    I just bought a slingbox and am looking for a way to connect my MacBook Pro to my tv. The problem is my tv is not HD and only has component inputs. If I buy the Apple Mini DisplayPort to VGA adapter and buy this:

    Would it work? Its a shame that Apple cut all their video adapters, they used to have RCA, s-video, component, dvi, and vga, now they only have dvi and vga :(

    I believe that will work. I have the mini-DisplayPort--VGA adapter and judging by the picture on Amazon, they're a match (the adapter is "female" and the Amazon connecter is "male," so that should work). I'd say that's your ticket.

    Curious... How is the OP gonna get analogue Component signals from the Digital only based mini DisplayPort???

    Specs, see attachment.

    I was under the impression that VGA was already an analog signal, no?

    By using Apple's Mini DisplayPort to VGA Adapter. Like they mentioned in their OP. :)

    So this should work fine then? :D The only thing that worries me is this line from the description:

    Note: This cable is NOT designed to work in anyway with a computer's input or output.

    Hopefully it will work....I will probably get it anyways and test it...

    This isn't going to work.

    Long answer: VGA is an analogue RGBHV signal. Your TV's component video input (in all probablity) is only Y/Pb/Pr (unless you have one of those odd TVs accepts multi RGB ins). These signals are not compatible.

    What the cable on Amazon is meant to do is to take a component out (or RGB) of a video device and connect it to the VGA in of a project. Most projecters can do this because they're set up to accept component or RGB over d-sub.

    What this cable won't do is covert your VGA (RGB) signal to component (TV) video, unless your TV is set up for it and your TV in all probability, is not. The signals are similar, but sync differently.

    Short answer: No. Don't bother.
