It depends on what exactly you're talking about.. The basic structure means 
that you would hook your DirecTV receiver up to the computer in 3 ways:

1) DTV's Video out --> computer's video in (usually video capture card; tv 
2) DTV's audio out (L/R) --> computer's line in (usually on a sound card)
3) DTV's "controller" port --> computer's serial port..

So, with these connections, video and audio flow to the computer, and your 
computer (with myth) can control the DTV receiver.. If your computer 
doesn't have a usable port (i.e., a Hughes HIRD-D0 I once had), then you 
would have to use an IR transmitter with something like LIRC..

You'll need "stuff".. For example, there is a script that we use to 
download our PPV movies, though currently there is no way to order the 
movies from myth.. Also, there is a script to do the Serial controlling, 
though you can make your own if you really want.. All of these things 
should be in the FAQ..
