not sure if this is the area to ask this question.......

DVD images look on motion pictures, and look better if you are use to NTSC standard (regular TV).
But it's actually worse than HDTV, HDTV resolution is over twice of that DVD.
DVD image frame is hardly high quality, DVD resolution is 480x480. You won't get any good quality for print on that.

Normal screen capture keyboard shortcuts (Command-Shift and 3 or 4 plus the spacebar) are disabled when using the DVD Player app. I suppose to protect copyrights.
You might be able to capture using a different app (VLC).
The image is not "high quality" because the DVD format (MPEG-2) uses 720X480 dimensions. Best you would get is a 72 dpi 640X480 image that wouldn't scale enough to make much more that a postcard print.

when the dvd comes out, load it into the drive, then open in in FINDER. DVD player will probably start automatically, so quit it, go to the DVD on your desktop and click on it twice. Set the window to COLUMN mode, go to the folder that has the quicktime file of your piece of video.

You can preview movie chapters of DVD's in this fashion, but usually there is no audio. Find the file that has your credits on it and drag it to the desktop to make a copy.

Open the file on your desktop in Quicktime, if you have Quicktime pro great, if not, stop and go get it. it's a great investment and you can't proceed without it.

Move the cursor right over the area of the file that has your credits in it. Resize the image as big as possible to give you the chance to move it around a bit until you get the best image possible.

Drag the pointers just right and left of your image to select as small a portion of the video as possible. This way when you export again, you won't be exporting a LOT of info. (This is why you need quicktime pro, can't export without it.)

Export AS A QUICKTIME IMAGE SEQUENCE into a folder you create on your desktop. When export is finished, go into that folder, again move into column mode, scroll through and find your particular image that you like best, drag to the desktop and throw the rest of the folder away.

There's your image. If the DVD export was good, you can actually get a good capture out of this process.

Good luck, hope this helps.

Boys, boys,
Actually it is all much simpler.
Download the Screenshot Plus widget from Apple.
Put a DVD in your computer and grab the shot you want.
Unlike other screengrabbers Screenshot Plus is able to grab from dvd's.
