    Dtivo Video Extraction, splitting, and muxing - Scripts, programs, and How-to's only

    Here's the place to put the various scripts and programs used to extract streams from the DTivo and get them into a usable format.

    Here's the patch and steps to disable scrambling.

    Currently it's only tested to work on upgrading a 2.0 install to 2.5.

    1) Get Tivolater25 from here. Read about it and make sure you understand what is going on.

    2) Download the attached zip file.

    3) Transfer the contents of the zip file to your tivo along with Tivolater. I suggest /var/update. You should end up with Update.tcl, Update.cpio.gz, noscramble.cpio, and noscramble.sh.

    4) Starting out in the same directory as the files (cd /var/update) issue the following command:
    Code:
    bash noscramble.sh
    After a while you should be upgraded to 2.5 and be scramble free.

    Keep in mind, however, that a subsequent update to the Tivo software may render your streams unreadable or, possibly, your Tivo unusable. Make backups!

    ==========================
    Now. If you already have 2.5 and don't want to nuke it for 2.0 then you can try the following. Now keep in mind that this probably won't work and you'll probably lose everything. Back things up. Any streams you currently have will become unreadable but new streams will be unscrambled. At a later date tools may become available that will allow you do descramble your scrambled streams.

    WARNING: The following may render your Tivo unconscious. Make a backup! This is untested and may result in problems. Any existing streams on your Tivo WILL be rendered unreadable.

    Download the attached file and transfer noscramble.cpio to your tivo into the /var directory.
    Run the following commands:
    Code:
    cd /var
    mkdir foo
    cd foo
    cpio -idm < ../noscramble.cpio
    gzip -d Hacked_utils-2.5-01-1.cpio.gz
    rm -rf /var/utils/*
    jpm -p Hacked_utils-2.5-01-1.cpio
    cd ..
    rm -rf foo
    /var/utils/tweakkernel /dev/hda`bootpage -b /dev/hda`
    reboot
    NOTE: the bootpage command is surrounded by back-quotes, the character on the same key as the tilde (~) on standard U.S. keyboards (usually left of the '1!' key). So, not ' or " but `. This is important.

    here's another way to disable the scrambling.

    copy the noscramble.o from the attached zip file to some place on your tivo (eg. /lib/modules), the run:

    insmod /lib/modules/noscramble.o

    you'll probably want to add this to rc.sysinit

    You can unload the driver if you setup rmmod:

    cd /sbin
    ln -s insmod rmmod

    then:
    rmmod noscramble

    it might take a few tries to unload if the driver is busy

    the source code is provided in the zip for those interested

    How to create a DVD from your TIVO

    How to Make A DVD from your TIVO

    Well - Success at last!
    I am holding in my hand my Toshiba Portable DVD player and it is currently showing the Wednesday Episode of Babylon 5 - "Midnight on the Firing Line!"

    * 3/31 Modified with BD38's resolution workaround - this shaves hours off the process by eliminating the muxing and transcoding steps*

    ***Important Caveat***
    You *Must* install NoScramble before performing recording the show to be extracted. Secondly, there is no way to unscramble a show that was recorded before applying NoScramble - oh well

    The steps to do this are:
    1. Set up your TIVO to send the data and PC to accept it
    2. Extract the TY Stream (Video)
    3. Process the TY Stream into Video and Audio files
    4. Process the Video and Audio so the conversion progs don't crash
    5. Change the the Video stream properties from 480x480 720x480
    6. Begin Import Process for Spruce Up
    5. Change the the Video stream properties back to a 480x480 from 720x480
    7. Author the DVD
    8. Burn Baby Burn


    Here is my how to file current as of 3/31

    BTW - With TYTool, you can skip steps 2 & 3

    MFS_Stream

    You will find attached all of the source files. The only one really different is mfs_stream.c, not the mfs_streams.c which was already there..., but you will need the others. I had to go through each one and convert each printf() to fprintf(stderr, ) calls.

    Otherwise any warnings etc would become part of the TyStream file and that would produce junk. Lots and lots of it.

    The mfs_stream program with an automatic priority setting to the lowest possible level. This means recording and playing comes first which is often what you would want anyway. I didn't run any speed tests. But here it is...

    ty2mpeg: One click extraction, vsplitting and muxing..

    I wrote this script to have my linux media server automatically vsplit and
    multiplex ty files which have been extracted from the tivo. In conjunction
    with edpuffmonster's mfs_extract_tivoweb module and jdiner's vsplit, you can extract, vsplit, mplex with a single click. Find included in this tarball a utility called mplex, a command line multiplexer written by Christoph Moar.

    The attached file is a gzip file.

    nfs client for TiVo 2.5

    This is posted elsewhere but is probably good here, too, since NFS is one of the primary ways to get video off the TiVo.

    Attached is an nfs client kernel module compiled against the TiVo 2.5 kernel. It works similar to the 2.0.1 module already widely available. It doesn't complain about a version mismatch on 2.5, though. It was compiled from the source included in the official TiVo release, with some minor modification due to some known problems in the Linux kernel regarding export of __kernel_thread in the 2.1.xx kernel series.

    Instructions are included in the file.

    AudioCheck...

    For those that asked for it. The AudioCheck program for helping in splitting dolby audio clips.

    This program prints out at which chunks in the stream the audio type changes. You then vsplit on these boundries and the audio and video should be extract correctly.
