I had been holding out hope that TiVo would repurpose the work they had done for Fire TV to bring DVR extender capabilities to the Android TV-based Stream 4K. Beyond whispers it was being explored at one point, TiVo PR seemingly left the door open. Or perhaps it was just my wishful thinking. Alas, it wasn’t meant to be. From redditor tivopm:
The TiVo Stream 4K capabilities and features were designed for the streaming player market. The company has no plans to integrate connectivity to TiVo DVRs.
The TiVo Stream 4K remains an economical Android TV solution – still just $50, which compares well to Fire TV and Roku, but now also available at Amazon (for efficient returns, should you change your mind). Although we’re still awaiting some fairly fundamental fixes…
