My mother just got a Tivo box this weekend and in the process of setting it up I came across the feature here of transferring recordings to a pc, and vice versa. I installed Desktop 2.5 on her computer and transfered one recording. I then selected an Mp3 to play on the Tivo box, again no problem. But when I went and moved some video files to the "My Tivo Recordings" folder, the only video that was shown on the Tivo box was the earlier recording that I had transfered over. In TiVo Desktop it says it supports WMV, and Xvid. Two of the video files I know for fact were WMV and Xvid. Is there any special reason these were not listed in the Now Playing List?
