I use xine, and others use totem to watch DVDs.
You need to install libdvd* and dvd* (some may be overkill but it is
simple to do) so ---.

To copy and shrink DVDs to mpg that fits on a CD I use mencoder.

I even found the reference to that on this list some time back.

The below script with a little tweaking for sizes works for me all the
time. (it needs the libs I referenced above as well as lame to
decode/rip)
--------------------------------------------------------
mencoder dvd://1 -aid 128 -oac mp3lame -lameopts br=96:cbr:vol=7 \
 -ovc frameno -o frameno.avi

mencoder dvd://1 -sws 2 -oac copy -ovc lavc -lavcopts \
vcodec=mpeg4:vhq:vbitrate=709:vpass=1 -vf \
crop=704:352:6:64,scale=1024:464 -o movie.avi

mencoder dvd://1 -sws 2 -oac copy -ovc lavc -lavcopts \
vcodec=mpeg4:vhq:vbitrate=709:vpass=2  -vf \
crop=704:352:6:64,scale=1024:464 -o movie.avi
-----------------------------------------------------------------

The first line rips the audio,
the 2nd and 3rd lines do a 2 pass rip of the video and merge in the
audio.  The quality is excellent.  Even though the name is .avi the
output is actually an mpg.
