"Great Price for all it does"
If you have this and a video cable it makes watching movies from you macbook easy and BIGGER. its a simple adapter for a good price. BUY IT!

"Works."
The image clarity isn't perfect but if you have a widescreen tv this adapter is probably right up your ally. I just bought it to watch movies i make on my mac, fun fun.

"Wonderful "It just works.""
Like most Apple products, this adapter just works, plain and simple. Plug it into your Mini DVI port and grab your S-Video or RCA Video cable and plug one end into the adapter and the other into your TV or VCR and you will have your computer screen on the TV. We have used this adapter to watch movies and TV from the built in Front Row on our Macbook as well as from Hulu and Fox On Demand in full screen. Definitely worth the few dollars the adapter costs. There is no configuration settings with the adapter that you need to tune up. I've used other non Apple laptops as well as converters on a PC and it was terrible trying to get it setup and get the resolution correct so it would look good on the TV. With the Apple adapter you just plug it into the port on your Mac and the resolution instantly adjusts. Perfection.

"Works perfectly"
I use it all the time, and it works exactly as expected. Completely user friends. Just plug it in and it auto-adjusts your resolution, or you can switch display modes to use multiple monitors. It's perfect for displaying images, or watching movies on a standard TV.

"Finally, the right adapter!"
Reviews are only good if you can learn something from them, so here's what I did with this adapter. Hopefully it'll help you figure out if it's right for you.

It took awhile to figure out which adapter I needed, and then it took awhile to get the right one, but this is it. I wanted to connect a 1.5 GHz Powerbook 12" (aluminum) to a Sony Wega 27" flat-tube TV and watch videos. At first, I though all I would need was a mini-DVI-to-component, and then I learned the difference between "component" and "composite." Didn't matter though, because what I actually needed was this, the mini-DVI-to-Video adapter. (For an iBook G4, I think you'll need mini-VGA-to-video.)

The "Video" stands for S-Video, and any generic S-Video cable will hook up to it. You don't need an expensive Monster cable for this job.

The video quality ranges from acceptable to great. Even though you can see the lines of pixels on such a big TV when you're looking at the desktop, videos recorded at DVD-quality *look* like DVD-quality. Videos (by which I mean legally-acquired TV episodes) encoded at less than DVD-quality look pixelated if they were originally digital broadcasts, for some reason, so while The Invisible Man (new) looks crisp, new Battlestar Galactica looks... chunky. From this, we conclude that that adapter itself works just fine, and it's up to your original file quality to determine how good it will look on the TV.

That said, the screen resolution is 800x600 while the adapter is plugged in, so I wouldn't recommend routing video from a 12" PB to a larger TV than 27" unless you don't mind a little fuzziness.

The adapter also comes with a composite jack, but I haven't used it, so someone else will have to review that aspect. :-)
