Quality of QT extraced from DVD

With the permission of the producer, I extracted a QT movie from a DVD. I have done this many times before and the quality has been excellent. From this particular DVD, however, the quality is excellent as well, except with any rapid movements, like a diver pumping their leg and the rapid movement of his flippers. Rapid movement creates a blurring which, when I freeze the frame, shows horizontal lines extending from the left and right of the blurred object; lines that taper out pretty fast. Yet, they are obvious when playing the clip on all rapid movements. Any ideas what this may be and how to reconsile the problem?

sounds like interlacing issues to me. try deinterlacing.

also, what tool are you using to extract the content? unless you use the custom "expert" export options, the default DV export or export to fcp is always going to result in a lower quality final product

I tried de-interlacing but no effect. Also, am using DVDxDVPro to extract source to QT. I don't think there are any options on extraction with this program. Any other extraction software suggestions?

there are TONS of options with mpegstreamclip:

FREE - and kicks the snot out of dvdxdv IMO

I downloaded the program and attempted to extract the media from the DVD with no success. When I attempt to download it in an mpeg format I get a box that tells me that I need to upgrade my mpeg-2 player. Apple's site does not even include a designated mpeg-2 upgrade and besides, I should not need one in that I have QT7Pro on FCP 4.5HD. I tried to extract the media in H.264 and, although I got a 1.3GB clip from it, I cannot open it. Is there a secret to this program or what?

i havent done it in a while, but my process always was:

1. rip dvd to a folder on your drive
2. open mpegstreamclip
3. file > open files
4. set in and out points
5. export to quicktime
6. pick desired settings
7. done

BTW, all the various "export to..."
settings bring up the same window, they just have different things auto selected.
you can pick any one you want and just modify the settings
