Just replaced the crashed HD on my laptop. Installed Windows XP Media Edition. Downloaded and installed Tivo DeskTop 2.6. Wirelessly downloaded 6 tv shows from my Tivo to my laptop. When I click Play Video from Tivo Desktop it opens WMP11 and shows the video as Now Playing, but I get no picture or sound. Same thing happens if I open WMP11 and point it to the Tivo files. I downloaded the VLC media player and get the same results. The Tivo files appear to be appropriate sizes, so I'm pretty sure they downloaded. I'm going on vacation in a remote area where I only get one tv station so I'd really like to be able to watch these shows at night.
