I'm running into some errors during the Tivo Desktop 2.6.1 installation on Windows XP. I've installed Quicktime, Java, and a MPEG2 codec. During install I get a Tivo Server Error window saying "The parameter is incorrect". And when I start Tivo Desktop I get another Tivo Desktop Error window saying "Unable to begin Tivo Desktop. The parameter is incorrect" and another window saying "The service did not respond to the start or control request in a timely fashion". I think the error is coming from some disabled Windows services. Does anyone know which services Tivo Desktop uses besides the Tivo Beacon service?
