When TiVo announced its TiVoToGo service last year, providing Windows users with a way to copy TiVo-recorded TV content to PCs, notebooks, and (ugh) Portable Media Centers, I thought it was a great idea. But now TiVo is taking this service to the next logical step, providing users of Apple's video iPod and Sony's PlayStation Portable (PSP) with the same capabilities. Because of licensing costs associated with the MPEG-4 video format that both devices utilize, however, there's a caveat: To copy TiVo content to an iPod or PSP, you'll need to purchase a utility from TiVo to perform the conversions. This utility should be available in the coming weeks, TiVo says
