Hi guys I have bought this item from ebay and I'm having problems with this item.
I'm trying to watch some movies with my family and I'm having problems.
I'm not getting any signal from my tv. I think the item is fine since my macbook's resolution changes to 800X600
I tried to change it to 640X480 (I think) the lowest possible resolution and it doesn't work, Nothing happens to the tv only in my macbook.
It's set to pal 50hz and everything I can think of.
Did I buy the wrong stuff?
I bought my macbook on 2007 Oct just before leopard came out.
Cheers!

Are you setting it to mirror or extended desktop when you're doing this?

I don't know what that means.
I just want to see movies in my tv.
I've searched around and it says it's impossible to have analog signal from a macbook but I thought that was what this adapter is for no?
