Can't take screenshot from iDVD?

[ashgreen]

We've recently been converting our family films from VHS to DVD. There are a lot of important and sentimental moments in these videos, so I'd like to take pictures from them. However, when I attempt to take a screenshot, it comes up as blocked out gray and white checkerboard. Is there any way to make it not do this?

I tried using command+Shift+4 and something in Terminal. I'm really, really not very computer savvy so if you tell me to go into Terminal again I need some seriously step by step directions.

Computer info:
Macbook Pro
OSX 10.6.8

Thanks for any help!

Hi,

For screen shots I use command + shift + 3

I've tried that as well (command+shift+4 is just the version with crosshairs).

Hi,

I was under the impression that ⌘-Shift-4 only took a picture of part of the screen and that ⌘-Shift-3 took the whole screen
Will just add that some applications, such as DVD Players may not let you take pictures of the screen.
You can also take pictures of the screen using the Grab application (in the Utilities folder).
