Thanks to ETSI, the specification is freely available. Simply get the latest 
ETSI EN 300 468 from www.etsi.org.

VDR will switch to a new library to decode the DVB SI information in the 
upcoming 1.3 release. Use it, no need to reinvent the wheel. If you are 
interested I can send you a current and corrected version via private mail.

The higher level code - building a database from the EI tables - is in VDR's 
eit.c. You will have to read the code.
