It's pretty easy, assuming you have a Series 2 Tivo. I've been doing it fairly often. First you need to install Tivo Desktop 1.9.3 and then enable the TivoComeBack feature. The easiest way to do that is search for VisualHub and use their enabler. Once you have that working, simply export from EyeTV as an MPEG2 file and put it into the TivoShows folder. Make sure you export the MPEG2 with the parameters outlined here: http://customersupport.tivo.com/LaunchContent.aspx?CID=4012D160-79C3-4238-96C8-A27B323D1413 or you can run it through VisualHub using the Tivo profile.
