DVD2One 1.3 or 1.4
DVD Shrink 2.3
Nero Recode 2.0.0.7
I haven't used DVD2one in a while, so I can't really speak for the newer versions, but the older versions (the ones that supported full disk copy) were not very good quality-wise when you tried to compress 9GB down to 4.37GB.
Now, it's gonna be very hard for any transcoding tool to do it. But my opinion was always that DVD2one looked worse.
DVD Shrink 3.0 B5 and Recode 2 are very close in terms of quality (mainly since they are almost identical). Recode 2 does have one very big advantage, however, and that is the ability to replace titles with a custom image or custom blank colored screen. Depending on what you replace, you can gain a lot of space this way. Select to replace titles with a plain black colored screen for the smallest file size.
Of course, other things that can help make way for more space for video is to remove audio tracks you don't care about. (DTS tracks are especially large and should be gotten rid off if its a long movie - like you said yours is.) You can also remove subtitles that you don't want, though they are generally small and removing them won't normally have a noticeable effect on the video quality.
Personally, I would try DVD Shrink 3.0 B5 first since its free. What have you got to lose? Compress it, then view it on your computer in WinDVD or PowerDVD and see what you think. You don't even have to burn it to a DVD. Completely no-cost option.
