Did you create an image file on the hard drive and view it yet? It may be the computer but more likely artifacts from the video conversion/compression to DVD. You said it was choppy on a DVD player?
There is much more to it than this, but it takes more bits per second to keep up with moving video than for static. What gets transferred as a video is playing is only what changes from frame to frame, if there is a lot of movement, like in a pan, all the pixels in the video frame get transferred, and you need a big pipe for that, especially HD. For still frames, basically not much is transferred, and you don't need a big pipe.
Not real numbers but, as an example, if a scene needs 80 bps to display smoothly with the resolution you want but the video pipe only supports 40, you will get chop. The solution is to reduce the resolution, i.e. the number of pixels in the video to the point where 40 bps will play smoothly. This is typically done with compression, which is a broad topic. DVDs is not a large pipe. Bitrates should be limited to about 9Mb/s maximum for compatibility. Now if the player has to deal with disk errors (burn anomalies) it may not be able to decode fast enough. Hence the suggestion to try a different media as one my not have as many errors than another.
Does your video, by chance, have several sound tracks or subtitles?

Stuttering in slow pans is notorious for showing flaws or illustrating how difficult it is to transcode/compress when trying to shoehorn video into too small a small box.
