+ENABLING XVID TO ENCODE USING MULTICORES
+----------------------------------------------
+The libxvidcore4 package that you can get through ubuntu or debian
+is version 1.1.0. They didn't enable multi-core encoding using this
+library until version 1.2.0. Since you can't get that in a package,
+you can build it from source easily. Since the xvid codec (this lib)
+is used by mencoder by rip_dvd in all of its xvid profiles (the default),
+you can speed up the encode process quite a bit if you enable multi-cores.
+Follow these instructions to enable the xvid encoding to use multi-cores:
+
+> wget http://downloads.xvid.org/downloads/xvidcore-1.2.1.tar.gz
+> gunzip xvidcore-1.2.1.tar.gz
+> tar xvf xvidcore-1.2.1.tar.gz
+> cd xvidcore/build/generic
+> ./configure --prefix=/usr
+> make
+> sudo make instal
+> cd /usr/lib
+> rm libxvidcore.so.4
+> ln -s libxvidcore.so.4.2 libxvidcore.so.4
+
+After you do these steps, when rip_dvd is running using any xvid profile,
+you will note with 'top' that the mencoder process is using > 100% of your CPU.
