PTV Upgrade for networking HDTV DVRs with Tivo

[HD Library]

PTVnet unlocks the power of your DirecTV DVR by enabling the unused USB ports on the rear panel, and providing you basic network connectivity to your TiVo. A PTVnet drive along with a standard USB 2.0 Ethernet adapter (and an optional wireless bridge) and you'll be able to communicate with your TiVo over the web to remotely schedule, sort, and prune your content faster than if you were sitting in front of it with the remote control! Additionally, we've included support for large drives (aka LBA48 support) and several other popular tools to enhance your TiVo experience (eg caller id right on your TV screen!). Lastly, telnet and ftp access is also provided for advanced users*.
