I need to update the tutorial for video usage but I saw bob mention this in another topic for when MC crashes/gives segmentation fault errors; ldd -d /usr/lib/jriver/Media\ Center\ 20/libJRPlayer.so
You can also try starting MC via mediacenter20 from the terminal and copy and paste the terminal contents here when MC begins giving you issues.
Here are the results, unfortunately it is way over my head.
