Things You'll Need
Instructions
Plug your TV tuner box into your Mac computer via USB. Slide the installation disk that came with the tuner box into the CD drive and click on "Install Software." Select the hard drive that you want to install the software and wait for the software to install. Restart your Mac to ensure that all the drivers properly install.
Connect your Xbox to the TV tuner box via the A/V cables available. Most tuners will support component connections, though the newer models will also support HDMI connections. Plug in the Xbox power only after the A/V connections have been made. Turn the Xbox on by pressing the power button on the front.
Press the connection button on the Xbox controller so that you have a remote to work with. Open the tuner software on your Mac and tell it to accept the incoming video feed. You can also select to record the feed but video eats up a lot of memory so be mindful of your storage limits.
Plug in an ethernet connection to the back of the Xbox and logon to Xbox Live.
