I used to have 3 directivo's all hacked for exporting recordings.  My
understanding was that the directivo's stored pretty much the straight
digital feed from directv.  The issue with tivo export was getting an
understanding of the MFS file system which tivo uses to store
recordings.  Once that was done, tools like tytool, and tydemux, and
now even vlc and mplayer, were developed to be able to read the files.
 wouldn't it be interesting to see what the stream coming from one of
these modified recievers was?  I'd love to be able to record espn hd
football on my mythbox.  no way to do that currently.
