TiVo Inc. and Nero AG of Germany were set to announce Monday that they will be launching a package that turns a Windows PC into a TV recorder, just like a TiVo set-top box. The kit will cost $199 when it goes on sale Oct. 15, and includes a remote and a TV tuner that plugs into the PC. The interface on the computer screen looks just like the one on a TV equipped with a TiVo box. It's not the first software that allows TV recording on the PC. That's been possible for years on computers equipped with TV tuners, and some versions of Microsoft Corp.'s Windows Vista operating system include the necessary software. But it will be the first time that both the TiVo interface and functions have been replicated on a PC. The Nero LiquidTV/TiVo PC will go on sale initially in the U.S., Mexico and Canada, but it could open up some markets where TiVo does not yet sell its set-top boxes.
