TiVo fought back in digital media tonight by launching the Series4, its long-planned overhaul of its DVRs. The new models center on a heavily redesigned, Flash-based and HD native interface that now puts online video services like Amazon VOD, Blockbuster and Netflix on a higher level than before; content available through those will appear in the same searches that spotlight regular TV shows. More Internet deals are also coming that will include Internet radio from Pandora and a mix of news, photos and status updates through FrameChannel.
