Regarding your Slingbox AirPort wireless bridge discussion near the end of the MGG#160, Apple shows such a setup in Apple Support article HT2044 “Using the AirPort Admin Utility to create a WDS network with multiple base stations.”

In the article, there are AirPort base stations connecting as clients (AirTunes sharing) and bridges (for a wired client) to an existing AirPort base station network. It does not mention 3rd-party WiFi networks, but a point-to-point bridge setup should work. The base stations can connect to existing WiFi setups like any client and then simply turn on bridge mode. See Apple Support article HT1731 and the AirPort Express Setup Guide: AirPort_Express_SetupGuide_5.1.pdf.

Ryan, thanks for setting the guys straight on using HDMI. They needed that.

You discussed connection of a MacBook Pro to Wide Screen TV in episode 190.

My MBP only has a DVI plug.  My TV has a computer input area that has a VGA connector and a DVI section shares the audio input.  I connect an adapter from DVI to VGA and use a VGA cable to the TV.

What is signal is my TV operating on, digital or analog.  The picture is great.


Richard:  In that setup, it’s working on analog VGA. The connector on DVI can have a small group of pins that include the analog signal. It’s those 4 pins surrounding the large flat blade-shaped one. All Macs with built-in DVI output include this analog capability, which is why the VGA adapter works. Analog-only is called DVI-A (for analog). The all-digital used on Apple’s displays is called DVI-D (digital), and the both-in-one connector used on your MacBook Pro is called DVI-I (integrated) because it contains the pins for both. Actually, it’s sometimes called DVI-DL because it supports dual-link displays like the 30-inch. Check out the excellent “digital visual interface” article on Wikipedia.

Regarding idisk vs dropbox. I use Windows Live Sync ( I know it’s microsoft, but it can sync large libraries among multiple computers. No cloud storage, but fine if you have a computer that’s left on all the time. Can also managed shared folders, so you can share with other users. Has Windows and Mac client software.

Thank you for the excellent explanation of the MBP DVI connection to Flat Screen.  I really appreciate it.


Regarding using an Airport Express as a bridge to a wired device- sometimes ignorance is bliss! I never thought that this would not work, so I just did it. I plugged in my Express near my entertainment center to use for Airtunes and I figured I might as well connect an ethernet cable to my Tivo, too. I works perfectly! I’m not very geeky, meaning I can’t explain anything about why it works, it just does.


I have a network of 3 Airport Express routers as part of a WDS originating from an Airport Basestation. One of these is these is used to bridge my TiVo via the Airport Express’s Ethernet port which is active for bridging the network.
