That's pretty much the size of it.

AFAIK that is true. But I don't think this is something you want to put in
the drivers. It should be a separate program or maybe a library.

The spec you want for DVB service information is ETSI EN 300 468

I recently added EPG parsing in iTele (well, 'now' and 'next' only, but
the structures are the same). The source code is available at
http://www.defyne.org/dvb/. If you're not a fan of C++ then look away now.
The files in there that you want are DPConnect/Streaming.hpp and the
PacketProcessor::processEIT method in DPConnect/TSHandler.cpp.

I doubt you can use it directly since I gave no thought to endianness 
issues. There is also a full DVB and MPEG SI parser called mpsys which may 
be of more use to you, although I found its code to be impenetrable. Find 
it on google.

But anyway, parsing this stuff is really quite easy ... have fun!
