Ok I haven't had any time to look into this, but I will try again. The
epgsnoop didn't work for me, but what I have found out is that the EIT
is supposed to be transmitted on a channel named EEPG. If you check
this page: http://www.lyngsat.com/packages/showtime.html it is (@
Showtime EPG). According to Lyngsat it is transmitted on freq. 11862,
using SID 2. I have tried to run 'dvbsnoop 2', but it doesn't output
anything. According to this post
http://www.sat-industry.net/forums/db-images/11274-problems-showtime-arabia.html
somebody have managed to get it working on Dreambox.
Here is some more info from dvbsnoop:

As I said earlier I am more than willing to make a patch for this
myself, I just don't know where to start yet.
