After several tries we have finally gotten a version of Tivoserver up, with integrated ffmpeg and mplex, that is not uber-buggy. There are still some bugs of course, but there were several bugs introduced in version 0.4 that were not there in earlier versions. Version 0.4.3 is the most recent version, so if you are using 0.4, 0.4.1, or 0.4.2 please upgrade :)
