Start simple. Put one or two .TiVo files downloaded from your S2 in the share directory and see if it sees them. Also try a mpg (mpeg2) if you have it. You may have video files that are incompatable with your S2 or the version of ffmpeg your using is too old, or you're not pointing to your ffmpeg.exe. What version of ffmpeg are you using with pytivo and do you have the full path with filename set in pyTivo.conf for ffmpeg? i.e. ffmpeg = C:\PyTiVo\bin\ffmpeg.exe Try this with the recommended simple conf file -> http://www.tivocommunity.com/tivo-vb/showthread.php?p=9682394, but make sure to include the full path to your ffmpeg.exe. Code: [Server] debug = true ffmpeg = C:\PyTiVo\bin\ffmpeg.exe [My Videos] type = video path = C:\Documents and Settings\Mike\My Documents\My Videos force_alpha = true I would also recommend moving your share directory out of your user space and into something like C:\TiVoVIDS or U:\Videos, etc. Just don't put them under your user directory in Windows. This should eliminate permission problems accessing them while running PyTiVo as a service under Windows.
