Macbook doesn't like HDMI anymore.

My Macbook's Mini-DVI port stopped working with an HDMI adapter, but it still works with a VGA adapter. Baffled.

Yesterday I was watching a movie on my TV playing from my 2011 Macbook Pro (Lion 10.7.2) using a mini-DVI to HDMI cable, which has worked flawlessly for the past 2 months.
I unplugged the cable, then plugged it back in, without rebooting or anything, etc., and now the Macbook doesn't recognize the HDMI connection (i.e.:nothing happens when I click on 'detect displays'). The TV recognizes the connection (it shows up under 'Inputs'), but not the Macbook.
Using the same HDMI cable and TV, I can connect from my wife's Macbook without a problem.
Using the same port and the same computer, and a mini-DVI to VGA adapter I can connect to a monitor, and even to the TV through its VGA port.
I have tried the whole thing on another TV with the same results.
So the cable works, the TV works, and the port works, sometimes.
I'm thinking software/configuration issues, but it's weird as the exact moment this stopped working all I did was unplug and plug in the cable. Ideas?
