Advertisements Am I the only one having this happen? All of a sudden WMP doesn't work any more on .tivo files. It loads the selected show and you see about a half of a second of it and then it quits. Is this another one of those expired certificate things? This particular PC is running Windows 7. Previously, as in a few days ago, it was working fine--I use it to check the quality of show copies I make with TiVo Desktop, but now it's not even working on files created back when it was working.
