Building the Tools for ripping Tivo media files onto VCD/SVCDs

  Note:  Though I've put a LOT of time into this, I have come to the
         conclusion that the current state of the Linux MPEG utilities 
         just aren't up to the quality of the Windows tools.

         I currently ONLY use the Linux tools to create the .bin/.cue
         files (vcdimager) and then burn the CD (cdrdao)

         If you've found other ways to get better quality out of the
         mplex, mpeg2dec, and mpeg2enc tools.. please let me know.

The following worked on Mandrake 7.0 and 7.2
--------------------------------------------


1) Required the installation of SDL-1.2.1
   ./configure
   make
   make install

   #I had to do a "make install" since older versions would
   #give errors with the other packages needed below


2) Required the installation of mpeg2dec-0.2.1-mjpegtools
	ftp://mjpeg.sourceforge.net/pub/mjpeg/
        cd libvo
        patch < video_out_YUV-patch.c 
   ./configure 
   make

   #copy the binary back to the main tivo directory
   cp src/mpeg2dec ..

3) http://download.sourceforge.net/mjpeg/jpeg-mmx-1.1.2.tar.gz
   ./configure
   make

4) Making mjpegtools-1.4.1

  ./configure --with-sdl-prefix=/usr/local/  

  NOTE:  From the docs, it would seem that running configure would
         work but..

       This didn't work:
         --with-jpeg-mmx=/mnt/hda2-80gig/tivo/jpeg-mmx/
        and this didn't work either
         --include=../jpeg-mmx
  
       Had to edit the makefile in both the mpeg2enc and mjpeg dirs:
          DEFS = -DHAVE_CONFIG_H -I. -I$(srcdir) -I.. -I../../jpeg-mmx  

   #copy the binary back to the main tivo directory
   cp mpeg2enc ../.. 
   cd mplex
   make
   cp mplex ../../..w

5) create the toolame file
   http://members.dingoblue.net.au/~mikecheng/layer2/toolame-02h.tar.gz
   make
   #copy the binary back to the main tivo directory
   cp toolame ..


Other Required programs (if they aren't already on your machine)
  - nasm
  - mpg123

6) Get the vcdimager v0.6.2
   http://www.gnu.org/software/vcdimager/

   ./configure
   make
   cp frontends/cli/vcdimager ..


7) Get the pccts133mr.zip files (required by cdrdao)
   unzip pccts133mr.zip 
   make

8) get the cdrdao-1.1.5

   ./configure --with-pcctsbin=/mnt/hda2-80gig/tivo/pccts/bin
--with-pcctsinc=/mnt/hda2-80gig/tivo/pccts/h

   #You need to install this as cdrdao needs to access the driver file to 
   #know what your CDR is capable of.
   make install

On a P200MMX w/ 128M of ram, I averaged  
41598 frames decoded in 9992.96 seconds (4.16 fps) 
it took 2hrs 46min.  The MPEG2 file is about 2.2 times
larger than the MPEG1 file
