Hi and welcome! Can't help you much as I have not done XBMC but someone else will be able to jump in.
I am just commenting on this:
That's a very rare setup you have there! They were the first adaptor cards ever made that has a standard PC network card fitted to an adaptor card that in turn fitted to the TiVo motherboard. These are called TiVoNET cards. They are a fairly slow transfer speed so I guess I can sort of comment that you probably won't be able to stream like people with a Turbonet or Cachecard can... But you never know your luck.
