Subscribers to the TiVo service will soon be able to "rent" movies from the Walt Disney Co. via their digital video recorders and view them on their television sets, the company announced Wednesday. It said that some films will be available in high definition. The service, which will require an Internet connection, will compete with similar services from Amazon, Apple, and Netflix. (The TiVo service involves a partnership with another online movie provider, CinemaNow.) Meanwhile, TiVo, which rarely displays black ink in its quarterly reports, said Wednesday that it had earned $3.6 million during its latest quarter, up from $835,000 from the year-ago period. It attributed the result, the best in its history, to lower operating costs. The number of its subscribers, however fell to 3.8 million, versus 4.3 million during the same period a year ago. It also said that it expects a net loss of $2-4 million in the current quarter.
