I don't have a DVI->VGA cable. I lost mine. So I can't hook the Macbook to the TV. I just bought Apacalypto from iTunes. I want to watch it on my TV. I have an XBox 360. It will only play WMV. How can I convert this M4V (which I did buy) to WMV? This is the first movie I have bought online. If I can't play it on the TV without buying another cable, it will be the last movie I buy online.
