Do any of those two help?
Especially:
Copied from my list of already answered questions.
Mroogle will have answered that question for you many and plenty of times.
MRoogle is quite a good tool to search this forums.
There is MacTheRipper, RipIt and Fairmount to rip (copy the DVD to your HDD while removing the copyright protection) the video DVD to your HDD.
Then there is Handbrake to convert the ripped DVD to a file like .mkv, .mp4 and .avi with MPEG-4 codecs like Xvid and H264, which are not meant for editing though, as they don't store every frame of the video (video DVDs use MPEG-2 as a codec, which also only stores every 15th frame and the frames in between are approximations).
After that you can use MPEG-Streamclip to convert the compressed video file to a .mov file encoded with the DV* codec, a codec iMovie can read and is meant for editing, as it stores every frame and takes up approx. 220MB/min.
You can also skip Handbrake and use MPEG-Streamclip for converting directly to a DV encoded .mov file from the ripped video DVD, but you need the QuickTime MPEG-2 component (19USD) to be able to access the MPEG-2 encoded video DVD footage via MPEG-Streamclip.
But it would save one encoding process.
(* Apple Intermediate Codec - AIC - is also possible and can be applied to the following section too)
OR
In order for you to edit your videos stored on the video DVD, you need to rip it via
MacTheRipper / RipIt / Fairmount, if the video DVD is copy protected (all commercial video DVDs are).
If it is not copy protected, you might be just able to copy the Video_TS folder onto your HDD.
Now there are two ways to convert the MPEG-2 compressed footage.
1. Get
Handbrake and convert the footage to either an .avi file with the Xvid codec (2-pass or Constant Quality of 100% and highest bitrate for video and audio) or an .mp4/.m4v file with the H264 codec (the same as with Xvid).
Then use
MPEG Streamclip to convert/export the .avi or .mp4/.m4v file to a QuickTime (.mov - CMD+E) file encoded with the DV codec or to a DV file (CMD+OPTION/ALT+E).
Both, .mov and .dv, can be read by iMovie.
2. Get the
QuickTime MPEG-2 Playback Component from the Apple Online Store for 20USD, open MPEG Streamclip, in there go to File > Open DVD and select your Video_TS folder on your HDD.
Then either export it as QuickTime with the DV codec or as DV file as explained in step 1.
This saves you one encoding process, therefore time and image quality loss.
Btw, SD is short for Standard Definition, meaning the broadcast systems PAL and NTSC, which has a pixel resolution of 768/720/640 x 576/480.
HD is short for High Definition, the new fancy high resolutions like 720p or 1080i/p.
A video DVD stores its video in SD.
Have fun.
