My laptop has always been able to play tivo files (shows or movies transferred from my tivo to computer) on windows media player. Then within the past year something happened and it will no longer recognize or play the tivo files when it had always worked before. Someone suggested using codec. I am not really sure how that works. I did download something someone suggested but it made the videos all blurry . I could hear but barely see the video. Does anyone know how to fix windows media player so it will play tivo files. The windows media player plays other files fine including other video files. If you could help I would greatly appreciate it !
