<sigh> This is not a difficult problem to solve. First off, the MacBook Air is _not_ a netbook. Netbooks are defined by their low-power processors (typically Intel Atoms). The MacBook Air has a full multi-core Intel I5 processor, which means it can do real work.
The best way to approach this is to look for a USB video input device, such as those from El Gato, which can input video to the Mac. From there, just use the El Gato application to display the video, or save it to disk. I don’t know if El Gato has a VGA-capable converter, but I do know they have devices that can input other video formats such as those common to current TVs and DVRs. I believe their URL is www.elgato.com or something similar. You may have to search for a suitable device that does VGA, and I suspect it won’t be inexpensive. Still, worth the effort. I would expect the conversion task to take a notable amount of processor horsepower since much of the conversion occurs inside the Mac. This means that that extra horsepower you get because the MacBook Air is _not_ a netbook will be very useful. You might also want to look at an alternate solution - an external monitor that the P3 and the MacBook Air can feed. While this solution means that you can only see one or the other video sources at a time, it might actually be less expensive.
