Hopefully this is the right place to put this, as opposed to the TTG forum. This morning, I installed Tivo Desktop 2.5 on my Vista machine, which went without incident. However, once it was installed, when I tried to open either a .tivo file, or an .mpg file I had made by running the .tivo file through DirectShow Dump, the video would not play in Windows Media Player...it would just come up on the first frame and freeze there. (Note that other .mpg files I had on this machine worked fine, leading me to believe this is a conflict with the specific .mpg codec that Tivo video files use.) Uninstalling TD allowed them to play again, but of course now .tivo files won't play. (Basically, I'm back where I started.) Here's the possible connector for all of this: I have ffdshow installed, primarily so I can play Divx and Xvid files in Windows Media Center using the Media Control Plugin. I think this might be what's causing this to happen...it's getting in the way of the Tivo codec doing it's job, or vice versa, or something. I'm not entirely sure, but I wanted to throw it out there as possible useful information. So, my question: anyone know anything about this, or how I might fix it? Ideally I would like to be able to keep ffdshow (if indeed it's the culprit right now) while still having TD installed. Thanks!
