My tinkering with my Tivo, has enabled me to extract the video from the Tivo onto my computer.

If you want to do this too, you need to have ethernet access to your Tivo.  There are several ways to do this.  I wrote up a page on my install if you are interested.

The first thing you need to do is install TyStudio onto your Tivo.

TyStudio - video extraction utility for your Tivo

If this is too hard or confusing for you, you might not want to attempt video extraction.

My warning to you about modding your Tivo is to Read the Instructions.  Read everything fully before starting, then read them again.  Make sure you understand what you are doing before you begin.

If you break your Tivo, don't come whining to me.  Haxxoring is dangerous work.

Once you have installed the software on your Tivo and have the binaries running on your computer
you should be good to go.  From what I can tell there are OS X, linux, and Windows clients
available for use.  I use the Windows version.

This is TyStudio editor, where you do most of your work.
To see what's on the Tivo, select 'Click here to load from Now Showing'

You should now see the contents of your Tivo.
Choose the show you want, and click OK

TyStudio Editor now grabs the information about the clip.

In a few minutes, you will be able to scan through the clip.
The cut start/stop buttons allow you to trim the parts you don't want out of the clip.

At this point, the video remains one the Tivo in it's weird format.
You have used the index to mark what you want the Editor to bring over.
When you 'Process' the video you are converting it to a DVD compliant format.

Make sense?
 

Tell the Editor where you want the mpg file.

And away it cranks.  Depending on the speed of your computer and length of the clip
 this process can take anywhere from 15 minutes to a couple of hours.

After processing you have an MPEG file you can watch in your computer or
burn onto a DVD for later viewing.

Good luck, take your time, and have fun.
