The biggest difference between the Comcast and DirecTV TiVo offerings is the ability of cable operators to exercise the same amount of control over the DVRs as they do now. While the DirecTiVo had several key features, including USB support to easily add a wireless network adapter, disabled by default, the relatively open nature of TiVo's Linux based architecture, made if fairly easy to enable them using resources freely available on the internet.
"Being able to port (TiVo) software into somebody else's box opens up a way to begin total integration of cable services into TiVo," CEO Tom Rogers says. "A lot of elements make it quite important."
So far the TiVo DVR interface is only available in the Boston area, and only works on Motorola DVRs. TiVo is reportedly already working on a version for other DVRs manufactured by Scientific Atlanta. Part of the reason for the limited initial availability is an effort to fix some bugs which both company's acknowledge are still in the software.
"Some of these are bugs that were known and were deemed to be reasonable to get the product out there," TiVo General Manager Jeff Klugman says. "We have several additional releases of software that are planned over the next several weeks and months to address those issues."
There's been no word on when the TiVo DVR upgrades will be available in other markets, but Comcast spokesperson Jenni Moyer said "We expect to begin to make it available in additional markets later this year." Of course even this limited release is already 2 years later than originally forecast by both companies. Limited testing began last October.
