Advertisements Up until now I've been able to play .Tivo files on my Windows 10 PC using Windows Media Player, but a few days ago Windows installed a new OS update, and now when I try to play the files I get a message saying "The selected file has an extension (.tivo) that is not recognized by Windows Media Player, but the Player may still be able to play it." Then it asks if I want the player to try to play it and I answer Yes. I then get an error message saying "Windows Media Player encountered a problem while playing the file." I tried uninstalling and reinstalling the MPEG-2 Video Extension and the K-Lite Mega Codec Pack 15.6.5 and still get the same error. Actually my preferred player to use would be Media Player Classic since I use it for everything else but I've never gotten it to work there. The file will start to open and I can see the correct running time at the bottom and I can scan through it but the screen is gray and I get no audio. I would really prefer to stick with the native .tivo file format instead of converting them to .mp4 format.
