DirectTV doesn't have a current box with TiVo software. They currently have their own DVR boxes, like most cable companies. I have not used one personally, so I can't speak to the quality of it.
Your current TiVo, or any other HD capable TiVo, will not work with DirecTV - they will only work with cable. This is because of the types of streams the boxes receive (MPEG2 vs MPEG4), as well as how they access the system you attach them to (i.e. CableCard vs Access Card).
The older TiVo DVRs for DirecTV won't be something you want. The original models are not HD, and the lone HD model isn't compatible with the newer satellites that transmit MPEG4. If you want to use an HD DVR on DirecTV today, their current boxes are really the only choice.
The good news is that DirecTV has gone back to TiVo and they're supposed to put out a new generation of true TiVo boxes that operate on DirecTV. The bad news is that they have been delayed time and time again. The exact launch date for these boxes is basically a moving target.
Hopefully this helps clarify things a bit for you.
