You're forgiven if you forgot that TiVo and Cox were once best buddies. They formed a partnership years ago, but that alliance quietly fell by the wayside. However, there are signs that it could come roaring back. Tipsters tell Zatz Not Funny (which has a good record with such leaks) that TiVo is close to launching Cox On Demand services. It's not clear whether this will simply rehash the DVR maker's Comcast technology or try something new. If the rumor is true, though, this could be heartening news -- you could spring for one of TiVo's nicer video recorders without having to sacrifice all the on-demand content that comes with your Cox TV package.
