Speaking at a White House screening of the new movie "Cesar Chavez" today, President Obama told the audience he couldn't stay to watch, but that he would get a copy on a "CD."

"I cannot stay for the screening. I've been promised by our director that I'm - or producer or somebody is going to get me the CD," he said.

"DVD," an audience member corrected him, to chuckles.

"Whatever. I'm a little technologically challenged. The DVD. The point is I'm going to watch it this weekend," Obama joked.

The First Lady and the Obamas' daughters are on their way to China, so "it's very lonely at home," he said. "Nothing better than to see an inspiring film."
