the only files I've been sending are scripts to display Caller ID info on the TV. Most forums prohibit talk of extracting video off the Tivo. But, I do plan on doing it soon. The only software I know does this is called ExactStream. There are some outdated links on google to this software, but I have a good bookmark at home. I will PM it to you later.

There is also a package called 25Xtreme which will open a bunch of back doors on your TiVo drive and may or may not be necessary to run to get ExactStream working. This will all be done over ethernet when I get around to installing a TurboNet card. I wouldn't dream of passing a 30 minute MPEG2 over 9600bps serial.
