Actually, I believe the problem is that DirecTivo's don't get the software updates like standalone units do. So they're stuck behind. (blame directv for this)
I'd recommend the combo box too if he could get it, however he'd forfeit the network capabilities he needs since there's no phone line.
Edit:
There is a trick that MIGHT work for the standalone box, but only after an initial setup call is placed.
1. Borrow someone else's landline and go through the initial setup process (use settings compatible with their service... for example, if they have Basic cable, select basic cable in the setup process.)
2. The next day, force a second connection at the friends house (if the second call wasn't already made). Your Tivo will be updated to the latest software revision. It will take a little while for the unit to update its software.
3. Take Tivo home, connect it to your DirecTV and network with a
compatible adapter.
4. Begin the Guided Setup again, using your directv settings, only this time enter ",#401" into the dialing properties. That is "comma-pound-4-0-1" without the quotes. This is a backdoor in the latest software versions that should bypass the phone and allow you to connect through the network connection.
In theory this should get you up and running, and you won't need the phone line again... unless you need to run the Guided Setup again for some reason.
