I own 2 Series1 SA Tivos, one has a TurboNet network card with 160GB hard drive, the other has a 30Gb HD only and it's used by my family for recording cartoons, children movies, etc. Hacking the Tivo is not an easy task, but once you get everything in working order it's just a breeze to download directly to your local hard drive, author and burn to DVD. Series1 are the easiest to hack and upgrade, you can even change the recording resolution to 720x480 so no conversion/patching is needed when burning to DVD. A neat application called TyStudio will edit and convert your stream from your Tivo to MPEG2 in real time, no need to download the TY files then edit, convert and upsample the audio to 48khz, TyStudio will do everything. On DirecTivos and Series2 things are a litle different, so you may want to check the forums at , they have all the info for DirecTivos and SA Series 1 & 2.
