If you wanna take the network adapters off eBay and sell them to me directly I'll give you $25 for them right now. (save yourself the eBay fees) I have the exact same set and could use another one to extend to another room.
If not I'll bid and see how it goes.
Edit: Was referring to the Network adapters not the TiVo. Glossed over the fact that you had two links.
Wording corrected for clarity
